Am I just an Idiot? (NPM install issue)

[Owil231]

When I run NPM install, sometimes it works, sometimes it doesn't.

Today I downloaded the latest update the generative art node, ran NPM install without any problems, generated several images with NPM run build, then saved and closed the project. when I reopened the project, attempting to run NPM run build produced several errors. Rather than spend hours troubleshooting, I reinstalled a fresh copy of the same version of the generative art node FROM THE SAME DAMN ZIP FILE I had used to successfully set up and run a project just minutes before, but when I ran NPM install, I got a long list of errors. Between the time I successfully ran NPM install and when I failed to run it, nothing about my setup changed — I didn't do anything else on my computer and I was using the exact same project files, just unzipped afresh.

I thought running NPM cache clean --force before rerunning NPM install might work, but it did not. I honestly have no idea what's happening here. Does anybody have any ideas?

The Errors I got after failing to run NPM run build were:

• npm ERR! code ELIFECYCLE
• npm ERR! errno 1
• npm ERR! art_generator@1.0.0 build: node index.js
• npm ERR! Exit status 1
• npm ERR!
• npm ERR! Failed at the art_generator@1.0.0 build script.
• npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

The Errors I got after failing to run NPM install were:

• npm ERR! code ELIFECYCLE
• npm ERR! syscall spawn
• npm ERR! file sh
• npm ERR! errno ENOENT
• npm ERR! canvas@2.8.0 install: node-pre-gyp install --fallback-to-build
• npm ERR! spawn ENOENT
• npm ERR!
• npm ERR! Failed at the canvas@2.8.0 install script.
• npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

My setup:

• Computer: Macbook pro 2018 (w/ 2.7 GHz Quad-Core Intel Core i7 and 16GB RAM)
• OS: MacOS Monteray 12.1
• Node JS version: 14.18.2
• Generative Art Node version: Main (as of Dec. 15, 2021)

Edit: npm (lowercase), not NPM

Update: as further proof of how inconsistent npm is for me, I just restarted my computer, repeated the whole process, and it worked. I have no doubt the problem will arise again, so any insight would still be much appreciated.

Thanks!

its a little tricky getting canvas installed. i had to use homebrew to install some additional libraries to support the node-pre-gyp stuff. I would check out the node-canvas README for the brew installation command. if you are on mac and using zshell you will also need to run a couple additional config commands to enable brew to work. after that you should be fine running npm i straight up.

Doesn't work for me. Did not do anything else?
