Can't get nodebots-interchange installed

dubaleeiro opened this issue 6 years ago · 5 comments

Hi,
There is no way I can get nodebots-interchange intalled on a raspberry pi zero w, even having formatted the SD card twice. I am triggering the command npm install nodebots-interchange from folder ~/.node-red like any other npm package. The package seem to be installed but when I try to run the command interchange following error msg appear:
bash: interchange: comand not found

This is the message I get after running npm install nodebots-interchange:
`npm WARN node-red-project@0.0.1 No repository field.
npm WARN node-red-project@0.0.1 No license field.

nodebots-interchange@1.3.0
updated 1 package and moved 3 packages in 139.879s`

Additional info:
npm --version is 5.6.0
node --version is v8.11.4
OS: "Raspbian GNU/Linux 9 (stretch)"

Thanks!

So there's probably a couple of reasons this may not work. 1. Install interchange using the -g switch to install it globally `npm install -g nodebots-interchange` 2 add "./.bin" to your PATH variable in your .profile or .bashrc file If it didn't fail when you installed, which looking at your report it didn't then one of the above should work.

Hello,
this is a bit confusing to me... sorry. Yesterday night I somehow managed to install it but today the command interchange does not work anymore.
Anyway... ist that so that you don't need interchange to connect a WS2812 Led ring with a Raspi Zero and an Arduino Pro Mini as a backpack? This is actually my case. I installed the backpack.ino via Arduino IDE and now the I2C adress 0x42 can berecognized by the pi.

However, now I am stuck to add the code to a Node-Red function node... is there any example on that?
Thanks a lot !!

Mostly you're using interchange to just install your backpack. If you've got that working then that will be fine.

There's not a node-red plug in for node-pixel but you can just create a function node / script node and then push code to it over a johnny-five connection.

I will try. Thank you very much!

@swiftmypants is this failing under the same conditions? On a raspberry pi? If so can you post what is happening for me and I'll reopen this ticket? If not, can you open a new issue?
