Can't install Animation Nodes.

Question

Can't install Animation Nodes.

OmarEmaraDev opened this issue 5 years ago · 114 comments

The following guide provides the installation instruction for installing Animation Nodes and the troubleshooting guide to troubleshoot your installation.

How to install Animation Nodes?

Disable then uninstall any version of Animation Nodes already installed.
Download a build of Animation Nodes from the Animation Nodes website.
Go to User Preferences -> Add-ons.
Press install and choose the build you downloaded.

Animation Nodes should now be installed and can be enabled. If you encounter any errors or unexpected behavior during the installation process, read the troubleshooting section below.

Troubleshooting

If an installation error occurred, Animation Nodes should show an error message with a description of the issue that occurred. Below, we present a number of issues the could occur and the procedure to fix them.

Can't find Animation Nodes in the add-ons list

The installed Animation Nodes build is corrupted. First delete the animation_nodes folder from the add-ons directories. See Appendix I. Then follow the installation instructions above.

There are multiple versions of Animation Nodes installed

Multiple version of Animation Nodes can't coexist. To fix this, remove all versions of Animation Nodes. You may need to manually remove the animation_nodes folder from the add-ons directories. See Appendix I. Then follow the installation instructions above.

Import Error: DLL load failed

Install vc_redist.x64 from microsoft's support center.

libpython3.x : Can't Open Shared Object File

Animation Nodes needs the python dynamic library in order to work. Install python3.x or/and libpython3.x from your package manager of choice.

Ubuntu

Ubuntu users may install libpython3.x from the deadsnakes PPA using the following commands. (Making sure to replace x with the target version.)

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update -y && sudo apt upgrade
sudo apt install libpython3.x

This build does not work at the moment

This could be caused due to a number of issue:

The build you are using was not built for the platform you are using. Download and install an appropriate build as described above.
You don't have the vc_redist.x64 library. See the section about "Import Error: DLL load failed" above.
You don't have the python shared libraries. See the section about "libpython3.x : Can't Open Shared Object File" above.

Animation Nodes depends on Numpy

Animation Nodes needs the numpy python module to operate. Install numpy to your python environment through your package manager or through other means. Official Blender builds have numpy installed by default, so you may also use the latest official Blender build to avoid the issue.

Animation Nodes needs at least Blender 2.80

The latest version of Animation Nodes only works with Blender 2.80. Install a newer Blender build.

Animation Nodes is built for another OS

An Animation Nodes build is built for a certain platform and will only work on this platform. Download an Animation Nodes build that is built for your platform.

There is a python version mismatch

An Animation Nodes build is built for a certain python version and will only work on this python version. The official Animation Nodes builds provided are built against the python version used by the official Blender builds. If your Blender build uses a different version, you will have to use a custom Animation Nodes build or build Animation Nodes yourself. Notice that Animation Nodes exists in the AUR for Arch users.

This is just the source code of Animation Nodes

The installed Animation Nodes build is corrupted. First delete the animation_nodes folder from the add-ons directories. See Appendix I. Then follow the installation instructions above.

Still can't install Animation Nodes

If you still can't install Animation Nodes, add a comment to this issue detailing the issue you are having and we will help you resolve your issue.

Appendix I

It is sometimes necessary to delete Animation Nodes from the file system yourself by deleting the animation_nodes folder in the add-ons directories. There are many directories in which add-ons can be installed, you have to go through all of them and remove the animation_nodes folder. The directories at listed in the Blender documentation.

Okay.

Answer 1 · 2019-12-06T19:47:55.000Z

@3DSinghVFX If you have the time, we need to debug the daily builds and see why they are not working with Ubuntu. Can you provide any information on the issue? Did the daily builds ever work on ubuntu?

Answer 2 · 2019-12-06T20:13:42.000Z

Sure :) I do not remember the exact date but this problem has been happening for the end of October. Tomorrow, I'll try to install AN from the daily build on the different Blender versions 2.80 to 2.8x and report back about this issue.

Answer 3 · 2019-12-07T04:42:32.000Z

@OmarEmaraDev

When I try to install AN from the daily build then it gave this error during enabling in the addon menu,
Next, I replaced the test_compile.cpython-37m-x86_64-linux-gnu.so with the file from the compiled build AN on my pc. Then it gave this error,
If I replaced the compiled files in the algorithms/hashing/ with the files from the compiled build AN on my pc, then it gave this error in the file in another folder,

It looks like there is missing python lib (libpython3.7m.so.1.0) in the online AN daily build.

Answer 4 · 2019-12-07T10:20:44.000Z

Can you try installing the libpython3.7 package then? Looking at an installation of Ubuntu 19.04, I can see the following files:

What is the default system python in Ubuntu 19.04?

Answer 5 · 2019-12-07T11:17:33.000Z

@OmarEmaraDev I have installed python3.7 (which that libpython3.7) then daily online build of AN worked without any error.

But I do not understand this problem. Does the daily online build of AN's lib path set to /usr/lib and the AN compiled on my pc with anaconda has lib path to lib-directory of the anaconda?

Answer 6 · 2019-12-07T11:26:30.000Z

@3DSinghVFX Is libpython3.7 a dependency of python3.7? Also, is python3.7 readily available from the official Ubuntu repository?

I don't fully understand the issue as well, but maybe the linker added the directory to the rpath of the library.

Answer 7 · 2019-12-07T11:31:14.000Z

Yes, libpython3.7 comes with python3.7. I do not know, maybe the latest version (18.04 or higher) of Ubuntu comes with python3.7 or python3.8.

Answer 8 · 2019-12-07T11:33:14.000Z

Ok. Thanks for helping with this! We will add that to the installation guide until we figure out a way to statically link Animation Nodes.

Answer 9 · 2019-12-20T03:00:40.000Z

Trying to update Animation Nodes from master zip, remove the old, bring the new, and after installing the module, cannot see it under addon list. What's wrong with Animation Nodes add-on installation, it seems problematic :(

I have Blender 2.81 and 2.82 alpha in separate folder. Trying to make this latest version running on Blender 2.82 alpha.

Answer 10 · 2019-12-20T05:16:41.000Z

Hi @enzyme69
From where you download the master zip file? I think you have installed the source code of AN by mistake. You can download the latest AN build zip file from https://animation-nodes.com/ or https://github.com/JacquesLucke/animation_nodes/releases

Answer 11 · 2020-02-02T20:54:12.000Z

So i am running 2.81, on windows 10, with AN downloaded from animation-nodes.com and i also have the latest vc_redist, and this is the error message i get when i try to activate AN after i instal the addon.

@limkork Are you sure you have the vc_redist.x64 2019 one?

Answer 13 · 2020-02-04T16:57:34.000Z

yes, I just double-checked and downloaded it again, same problem :(

Answer 14 · 2020-02-08T06:26:42.000Z

quick update, i got it working, i did two things:

one, i went in to C/appdata/blender/addons and removed the AnimationNodes folder from there, and i also redownloaded vc_redist for the third time, but this time i installed as administrator.

Im not sure which one of those cracked it, but at least it works!

Answer 16 · 2020-02-22T20:42:12.000Z

@eTaernis I can't replicate the issue. Can you manually remove the animation_nodes folder in /home/etaernis/.config/blender/2.83/scripts/addons/ then reinstall the addon?

Answer 17 · 2020-02-23T00:28:10.000Z

@OmarEmaraDev That did not work, so I deleted everything, re-cloned the repo and compiled, now it works - thank you! git status did not show any problems, but it seems like there was something wrong with extranodes - sorry, my bad.

Hey @JacquesLucke could you please upload version 2.1 compiled with python 3.7 for linux also? I'm having an issue when trying to compile it myself Cython is not installed for this Python version. Despite having installed Cython for python 3. I'm on Ubuntu 19.04.

Answer 21 · 2020-04-26T20:41:52.000Z

@jack1223233244 The builds we offer are already compiled for 3.7:

@OmarEmaraDev The "v2.1 Blender 2.7x*" and "v2.0 Blender 2.7x" builds seem to have been compiled for version 3.6.

Answer 23 · 2020-05-03T21:11:39.000Z

@jack1223233244 The 2.7x series used 3.6, so that's why we built against Python 3.6.

1 i found can install animation node for blender2.79 last official build
Animation Nodes + Extra Nodes for Blender 2.79 - Linux OS
so i think. you can add this download link to you site download page. i couldn't find this result yesterday ago.
2 i found to how to compile animation node for blender2.79 and linux?
Setup Environment on Windows
yes that version for windows OS. no result on linux page. but i did this.
sudo apt install cython3
that command in animation node sources directory.
python3 setup.py build --export --noversioncheck
but have problems, made animation node to version py38. =(
latest blender2.79 is python3.7. ok i checked python3.7 install. but sorry i tired for altinstall doesn't work on my system. method is Python-3.7.5.tgz using.
sudo make altinstall
but doesn't help anymore. you can get error on ubuntu 20.04.

@shridhar2011 I have tested those builds for Blender 2.79 and Blender 2.83 on Ubuntu 16.04, they are working.

Did you remove the old AN before installation?

Did you try the latest build of AN https://github.com/JacquesLucke/animation_nodes/releases/tag/v2.1-for-blender-v2.83-cd-build?

Can you please run the Blender from the terminal, and show the screenshot of the terminal (error)?

Does the error occur?
Is libpython3.7 installed?
What does ldd test_compile.cpython-37-x86_64-linux-gnu.so print? This file is available in the root of the Animation Nodes add-on directory.

Answer 45 · 2020-08-20T17:04:21.000Z

I had the same "This build does not work at the moment" error on a linux system running python3.8.

The problem is that you need to compile AN with python3.7, and even though the official blender builds come with their own python3.7, they lack libpython3.7m.so.1.0, which is required by test_compile.

In other words, the only way to have AN running on a linux system is to have python3.7 installed, plus blender and its own python3.7.

"Animation Nodes needs the python dynamic library in order to work. Install python3.x or/and libpython3.x from your package manager of choice."

This is not entirely correct: you need python3.7 and not python3.x.

Luckily in my system libreoffice comes with libpython3.7m.so.1.0 so I just run this command to have AN working:

ln -s /usr/lib64/libreoffice/program/libpython3.7m.so.1.0 /usr/lib64/libpython3.7m.so.1.0

just a workaround.

Anyway the AN developers should fix this problem or stop distributing builds that work only in a specific environment (it is not really nice to have this page, a closed issue, indicated in the manual as a guide for troubleshooting a problem which has not been even addressed).

Hope this helps,
andrea

ps: this part of the error message is funny, though: "It is possible that you have a build for the correct platform but it still does not work. We experienced this mainly on linux."

Answer 46 · 2020-08-21T09:29:01.000Z

Yes, that is correct. The right steps that worked for us:

Download v2.1 for Blender 2.83 LTS (Python 3.7) and add in add on folder
Install python 3.7 but you would need to change bashrc to make it use only 3.7. Else, it doesn't work
Install libpython3.7
./blender -b --python-console
Import bpy
bpy.ops.preferences.addon_install(filepath='animation_nodes/init.py')
bpy.ops.preferences.addon_enable(module='animation_nodes')

Answer 47 · 2020-10-28T16:35:56.000Z

The latest version of AN 2.2 cant be installed with 2.91 on Linux (Debian). Blender 2.83 and AN LTS version works on the same system so it seems to me that either Blender 2.91 is the issue or AN 2.2 compilation is the issue, at least on Debian Sid.

Hi sorry i did not provide an error

Answer 50 · 2020-10-29T08:49:34.000Z

@gerroon Do you have libpython3.7 installed? Is it linked correctly?

Answer 51 · 2020-10-29T15:27:46.000Z

Debian Testing does not come with libpython3.7 unfortunately nowadays, and I looked around to see how I can get it, it seems not easy to install it without breaking stuff.

In any case though, if libpython is the issue how come AN 2.1 (Python3.7) LTS works with 2.83 on the same system? These are still Python3.7

I am using Blender zip installs, not systemwide install so it is using Blender's own Pyt distribution.

Answer 52 · 2020-10-29T16:49:06.000Z

@gerroon Can you try the AN 2.1 version with Blender 2.91? It should work. That should tell us if the problem is about Blender or AN.

Answer 56 · 2020-10-29T19:25:38.000Z

@gerroon I don't understand why 2.2 doesn't work while 2.1 does. But the problem seems to be clear. libpython3.7 needs to be available. I don't use Debian unfortunately, so I can't help with the installation procedure. Maybe somebody else can help with this.

Answer 57 · 2020-12-03T11:44:24.000Z

@gerroon Did you ever get animation nodes working 2.1 or 2.2? It no longer works with Ubuntu 20.04 and the new Blender 2.91.0 (final) Everyone says everyone else needs to include libpython3.7 but no one wants to include it. I've asked Blender, Snap, Flatpak, and AN. Not sure what changed so drastically to cause such an issue. (Installing python ppa's are known to break more than it fixes)

Issue: with history
#1595

Answer 58 · 2020-12-03T17:10:00.000Z

@stillpointx You need to build libpython3.7 yourself unfortunately. I am also not sure why this sudden need occured.

Answer 59 · 2020-12-04T01:08:49.000Z

@gerroon thanks for the information, that's really unfortunate, oh well it was fun while it lasted (I guess all things must come to an end ahhh 2020 just keeps getting better) not many people will know how to build libpython3.7 (me being one) .

@3DSinghVFX Do you know if Animation Nodes + Extra Nodes has the same issues / requirements to build libpython3.7 to work in Ubuntu 20.04 and Blender 2.91.0?

Answer 60 · 2020-12-04T11:54:01.000Z

@stillpointx Hi...
If Blender 2.91 is using Python 3.7 (that comes with the build) on Ubuntu 20.04 LTS (has Python 3.8), then you need to build Animation Nodes.
So, to build AN,

Install the Anaconda (Python 3.8).
Create a new environment (say myenv) and activate the myenv.
Then install Python 3.7 and Cython using the conda commands.
Now, go to the AN source code directory and build AN using the command python3.7 setup.py build --export.
Do step 4 to build AN+EN.

Answer 61 · 2020-12-08T13:38:10.000Z

WOW!!! that is a lot. Something major must have changed (Due to the fact that Animation Nodes works with Ubuntu 20.04 and Blender 2.8x "out-of-the-box" but not with Ubuntu 20.04 and Blender 2.9x).

Answer 62 · 2021-01-07T06:45:21.000Z

I am using Blender 2.9 I have created successfully downloaded and utilized the animation nodes add on to create an animation, however whenever I hit the render button Blender crashes, I have a RTX 2070 and am saving the image sequence to a brand new 8TB external hard drive so I know the hardware is not the issue, furthermore the crash file indicates there is an issue with the add on, and I have no problems rendering when the add on is disabled via preferences. Any help troubleshooting so I can actually render what I have created using the add on?

thanks,

Stuck in Limbo here, Omar.

Installing on 2.92: Animation Nodes requires minimum 2.93.!! What?

But latest 2.93 all failed to install AN or SV for that matters. Then I can't really use Animation Nodes.

As for today I can install into 2.92 RC and Mac. Thanks Omar!

I had the same problem. Manjaro install Blender 2.92 with Python 3.9. I tried to compile AN it myself and it worked, but ask me for blender 2.93. Is there a place where I can change than number version to add 2.92?

Thanks!

Thanks @OmarEmaraDev Compilation worked and now it didn't complain about the version, but I have this error:

AttributeError: module 'bpy.props' has no attribute '_PropertyDeferred'

I imagine that's because that property is new to the API on 2.93. Is there any way in which I can compile a version for 2.92 with Python 3.9?

Thanks!

Answer 68 · 2021-03-07T05:07:43.000Z

@deimidis You can revert 4b0f5f8.

Answer 69 · 2021-03-07T22:31:25.000Z

It passed that problem, but there were other one:

ValueError: bpy_struct "an_FontSocket"registration error: display could not register

Don't worry, I will wait until versions get aligned.

Thanks!

Update: I done it. Just download 2.2 from the tag, and compiled it again with python 3.9. I still cannot tested too much, just see the panel and the menu. Thanks for all your help and your work

Answer 70 · 2021-03-13T06:49:07.000Z

Can anybody send me a link or explain me, how i can compile AN myself on a mac?

Answer 71 · 2021-03-13T12:06:53.000Z

@luckychris Just install Cython, then execute python setup.py build --export --noversioncheck. This will create a zip file that you can install.

Answer 72 · 2021-03-13T13:07:02.000Z

Can anybody please help me ?
I've already tried building it myself, tried the build in the animation nodes page and nothing, still getting the same error message

Answer 73 · 2021-03-13T15:14:39.000Z

@byjosue Is this with latest Blender daily build?

Answer 74 · 2021-03-13T17:47:39.000Z

Yes, I was using the latest, after that I tried uninstalling and installing animation nodes and tried various builds of animation nodes, one of them worked. Thanks for the help anyway

@luckychris Just install Cython, then execute python setup.py build --export --noversioncheck. This will create a zip file that you can install.

thanks omar, that was very helpful. I did this now myself and it worked but was a lot of work for someone, who never made this. Just a proposal: Why don't you provide compiled versions of animation nodes for different python versions? I think for you it is just one setup more for automated build, isn't it? I think not every artist/user of blender is capable in doing this and maybe not willing to do it. And if you would have provided it i bet you would even have more users of your amazing animation nodes which is really fantastic - but in my case - hard to install at all.

and believe it or not ...your "just install cython and..." took me 3 hours to do so and i had some errors messages in between which let my hair turn even more gray....

Answer 77 · 2021-03-16T14:23:00.000Z

@luckychris We have versions for 3.7, 3.8, and 3.9. I don't think anyone uses older versions, so I think those are enough.

Answer 78 · 2021-03-30T16:25:01.000Z

After runningpython setup.py build --export --noversioncheck, I get this error:

Answer 79 · 2021-03-30T16:59:36.000Z

@scottdmilner hmmm, I am not sure to be honest. Seems like a correct syntax as far as I can tell. Which python version is this?

Answer 80 · 2021-03-30T17:41:47.000Z

@OmarEmaraDev That's the issue, haha. Using Python 3 on MacOS is a bit of a weird setup right now, so I went through and aliased everything to my Python 3 installation and it worked fine.

Answer 81 · 2021-03-30T17:56:49.000Z

@scottdmilner Maybe python is actually a symlink to python2 or something. Anyways, good to see it worked.

do you happen to know which build it was? I'm getting the same issue.

Answer 83 · 2021-10-03T10:57:32.000Z

so for whatever reason, my animation nodes got corrupted somehow, and now when I try and re install it after removing the old version, it doesn't let me and gives me this error

:

Answer 84 · 2021-10-03T11:38:48.000Z

so I re installed blender, and got the latest build of animation nodes + extra nodes, but now it says that it isn't made for my operating system, even though it is a Mac build and I am using a MacBook Air M1 2020 and running macOS Big Sur:

Answer 85 · 2021-10-03T11:59:17.000Z

@GoldenAdrien That's probably because that build is for x86 Mac. You need an Arm build for the M1 Mac. There is an official arm build here: https://animation-nodes.com/#download

Answer 86 · 2021-10-03T21:15:55.000Z

What is weird is that it was working until it randomly corrupted yesterday

Answer 87 · 2022-06-08T18:48:42.000Z

Hi, I can't get the Animation Nodes to install on Blender 3.1.2 at all (Intel based Mac OS12.4) https://animation-nodes.com/#download. The reason seems be this version of Blender uses Python 3.10.2 and the latest Animation Nodes only supports Python 3.9.7. An error message shows on attempt to install.

Is there a version in development?
A number of 3rd party add ons seem reliant on this AN add on, and I've got stuck.

Answer 88 · 2022-06-08T20:00:51.000Z

@MetalAdvatar The "Latest" version in the download section uses 3.10, so this should work. You probably downloaded the LTS version, which is 3.9.

Answer 89 · 2022-06-09T08:57:46.000Z

Thank you Omar! That sorted it. I was trying to install the the LTS version.

It was just a UX issue from the website, it looked like there were only 2 downloads under "Latest", although I should have twigged there were actually 3 download buttons.

PS. Sorry I only notice this discussion was actually closed after commenting, but thank you for your reply. That was most helpful.

Answer 90 · 2022-09-01T17:24:36.000Z

@OmarEmaraDev @MetalAdvatar

Hey hello !

I tried installing it today and I got a different message since 3.10 isn't the issue anymore.

Appreciate any help

Answer 91 · 2022-09-02T06:51:40.000Z

@AssezAC I am guessing you are on MacOS. Are you on x86 or an Arm one? Did you make sure to download the appropriate version for Mac?

Answer 92 · 2022-09-02T13:22:03.000Z

@OmarEmaraDev I'm on an M1 so ARM right ? I couldn't find any choice, just the "latest" button which is 2.3 I guess...

Answer 93 · 2022-09-02T13:36:19.000Z

@AssezAC Yes, you want the ARM one. However, the latest version is only x86 for now. The only official build for ARM is the LTS one for 2.93.
You can, however, compile it yourself or use builds created by other users. See #1836.

Answer 96 · 2022-09-07T14:41:15.000Z

@Veraellyunjie Looks like we don't support OpenBSD, not sure if that requires any special handing somewhere or can just be enabled. The last errors are because you are executing the python script as a shell script, which invokes the imagemagick import program.

Can you open a separate issue for OpenBSD support or submit a patch if you can?
