Answer 3 · 2019-12-02T14:28:35.000Z

Hi there,

I had a similar issue. I upgraded to OSX Catalina. Then when doing node-gyp build I got the error as in below. I realised Catalina does not take the old 32 bit python previously installed, so I installed Python3. However, even after changing the alias for python, verifying PATH and even enforcing node-gyp build --python=(python3path), it seemed as if node-gyp was still looking for python v2.

The solution was to reinstall python2 for 64 bits.

% node-gyp build
gyp info it worked if it ends with ok
gyp info using node-gyp@6.0.1
gyp info using node@10.16.2 | darwin | x64
gyp info spawn make
gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]

I have the same issue

Answer 5 · 2019-12-06T11:17:13.000Z

Please look at this article from 2019: https://spin.atomicobject.com/2019/03/27/node-gyp-windows/

On Windows, you have to use Python 2.7 and Microsoft Visual Studio 2015:

Python 2.7: 'Python 2.7.0 was released on July 3rd, 2010.'
Microsoft Visual Studio 2015: 'July 20, 2015: Visual Studio 2015 (“VS 2015”)'

Latest version December 6, 2019; Python 3.8 (October 14th, 2019), Visual Studio 2019 (April 2, 2019)............

Answer 6 · 2019-12-06T12:03:52.000Z

please stop reading old articles and assuming they indicate the current state of a piece of software, the date is even in the URL and it's 9 months old. see the node-gyp README for current state and if you have an old version, update it and try again, same with npm which can be updated with npm i npm -g and will bring in a newer version of node-gyp.

Answer 7 · 2019-12-06T12:20:29.000Z

9 months ago is an old article in your opinion? Of course I followed the node-gyp README. Which did not fix my environment. Here is a more recent discussion (with a solution that worked for me); https://stackoverflow.com/a/57763427/4234891

Answer 8 · 2019-12-18T17:26:42.000Z

You do not need Python 2.7 in order to run node-gyp. Python 3 has been supported since version 5.0.5. If you have verified that your issue is python related, as in that node-gyp is trying to run a script which contains errors according to the python 3 interpreter, then try the following:

Update your global node-gyp install. npm install -g node-gyp
Update your npm install. npm install -g npm

Both modules are separate, npm will have its own copy of node-gyp. If you are trying to link a local package, for instance, npm will use its own copy of node-gyp. However, if you run node-gyp from the command line, it will use the other.

Of course, all of this is irrelevant if you don't have a valid installation setup. You will need build tools, as the previously linked articles mention. Windows voodoo dictates that you will probably have to mess around in order to get everything setup on the runtime side. However, you do not need python 2.7.

Previously I had started an Issue to suggested node-gyp should turn to python3. Couple of weeks ago, one of the contributor of node-gyp replied to me, saying that node-gyp now support pure python3. So I think there was no doubt that articles about python2 would be out of date

Answer 10 · 2019-12-23T17:44:16.000Z

I ran into this on Win10. It was a pretty crummy experience. The Node v13 installer tried to install some node-gyp dependencies + Chocolatey, opened a command prompt which flashed an error message, then the window flashed away with no further error.

When I tried to npm install for an application, it broke when the node-gyp build for node-sass trying to find python2 and defaulted to python.exe which was Python 3.8, and broke on a print statement. I worked around it by installing Python 2.7, and creating a batch file called python2.bat with the following contents and adding its location to my PATH variable:

py -2 %*

BUT, because the Node installer failed to install all those dependencies for node-gyp, I also had to install VS build tool 2015 (v140) and 2017 (v141) and launch npm install from my VS build prompt to get it all to work correctly. I hope this silly workaround helps someone else though.

Answer 11 · 2019-12-23T17:48:38.000Z

Python 3.8 [...] broke on a print statement.

You are using a version of node or node-gyp that does not support Python 3. This was fixed a long time ago.

Python 3.8 [...] broke on a print statement.

You are using a version of node or node-gyp that does not support Python 3. This was fixed a long time ago.

Looks like node-sass has a direct dependency on the outdated node-gyp 3.

Answer 13 · 2019-12-23T18:14:49.000Z

@cclauss You're right, it's an issue with a dependency and different than the one in the bug report. It's unfortunate that these errors appear as node-gyp errors. Thanks for the correction and thanks @richardlau for pointing out the potential issue with node-gyp. I'll file a bug report there.

End of Life of Python 2 is TODAY. Can this issue be closed?

I'm happy for you to make that call @cclauss, and on most things Python.

Answer 17 · 2020-01-05T00:45:46.000Z

Even now when I try to install Current: node 13.5.0 on Windows it comes up with this saying it requires Python 2

Answer 18 · 2020-01-05T00:57:57.000Z

please stop reading old articles and assuming they indicate the current state of a piece of software, the date is even in the URL and it's 9 months old. see the node-gyp README for current state and if you have an old version, update it and try again, same with npm which can be updated with npm i npm -g and will bring in a newer version of node-gyp.

If you consult node-gyp README here Option 1 directs you to the windows-build-tools page which says "If not already installed, it will also install Python 2.7, configuring your machine and npm appropriately."

Is it possible to avoid Python 2 or not?

Answer 19 · 2020-01-05T06:28:41.000Z

Please follow option 2 to use Python 3.

Answer 20 · 2020-01-05T12:42:22.000Z

Please follow option 2 to use Python 3.

Under Option 2 it says "If the above steps didn't work for you, please visit Microsoft's Node.js Guidelines for Windows additional tips."

At that link it says under Prerequisites "Install Python 2.7 (v3.x.x is not supported), and run npm config set python python2.7"

I don't want to install Python 2 as I have Python 3 and I don't want to mess that up. I am trying to install Node.js so that I can run ESlint and Prettier in Visual Studio Code.

Answer 21 · 2020-01-05T13:40:26.000Z

Which of the steps above don’t work for you?

Answer 22 · 2020-01-05T18:25:10.000Z

Which of the steps above don’t work for you?

Admittedly I have not yet tried the steps in Option 2 because I am still doing some research and don't want to mess things up.

Am I correct in thinking that if I am to get this to work, I need either Visual Studio Build Tools or Visual Studio 2017 Community? I am in a team of 8 and so if we all tried to use this set up we would require an enterprise license for either as discussed here and here. That license would be around $250 a month. Visual Studio Code, Python or Node.js do not require such a license themselves so this seems a bit odd.

Can I get away with not installing the additional bits for node to compile npm modules from C/C++? How can I find which modules require this?

Answer 23 · 2020-01-06T12:54:57.000Z

Even now when I try to install Current: node 13.5.0 on Windows it comes up with this saying it requires Python 2

Fixed via nodejs/node#31221.

To answer my own question, I installed Node using the setup wizard and then got ESLint and Prettier to work in Visual Studio Code without installing the support for native modules (i.e. Python 2, Visual Studio Build Tools or Visual Studio). Thanks

Answer 25 · 2020-03-25T14:21:58.000Z

Closing. gyp ERR! node-gyp -v v5.0.3 only supported legacy Python.

Python 3 is now supported in both node-gyp v5 and v6

Answer 26 · 2020-05-16T10:15:17.000Z

Is node-gys still required only python 2.7 ?

Answer 27 · 2020-05-16T10:43:33.000Z

This issue is closed. https://github.com/nodejs/node-gyp#on-unix

Python 2 died on 1/1/2020.

Answer 28 · 2020-07-10T16:07:49.000Z

I just tried to npm i on a project that was Angular 8, moving to 9. Could not continue until I added windows-build-tools, which installed Python 2.

@Zunnurayni Please install Python from the Microsoft store and then try again.

Answer 31 · 2020-07-27T18:25:56.000Z

If it's an option for you, backup your package-lock.json, remove it, and then try an install again.

HAD SIMILAR ISSUES BUT GOT THE SOLUTION:

first make sure you have python installed. (if you don't, install your version from this link https://www.python.org/downloads/release/python-385/ )
npm install --save bcrypt-nodejs
npm uninstall --save bcrypt
npm install
I HOPE THIS WORKS FOR YOU.

gyp ERR! node-gyp -v v5.1.0

Current release is v7.0.0

Answer 35 · 2021-05-22T19:25:27.000Z

This bug still lingers in 2021 -- because old versions of node-gyp linger. On my system, these steps resolved the problem (don't know which one was needed)

From administrator prompt on Windows:

npm install -g node-gyp
npm install -g npm
yarn install

All of these were run from the project folder containing the yarn configuration file and from the same adminstrative prompt.

But then yarn fails.
