node-canvas on Heroku

Question

I have a discord.js bot and it runs on Heroku. I added canvas just now, and now the bot is failing to build.

This is the log:

-----> Installing dependencies
       Prebuild detected (node_modules already exists)

       > canvas@2.6.1 install /tmp/build_c8ad4f45_/node_modules/canvas

       We're sorry this build is failing! You can troubleshoot common issues here:
       https://devcenter.heroku.com/articles/troubleshooting-node-deploys
       
       Some possible problems:
       
       - node_modules checked into source control

       - Node version not specified in package.json

       Love,
       Heroku

I already installed node-pre-gyp as the log suggested, and nothing changed. Here is package.json:

{
  "dependencies": {
    "canvas": "^2.6.1",
    "discord.js": "^12.4.1",
    "dotenv": "^8.2.0",
    "firebase": "^8.1.1",
    "firebase-admin": "^9.4.1",
    "node-pre-gyp": "^0.11.0"
  }
}

Does anyone know a solution to this?

Issues with `node-pre-gyp` are often associated with tracked `node_modules/` directories. Have you committed and pushed that directory to Heroku? It looks like maybe you did: "Prebuild detected (node_modules already exists)". — ChrisGPT was on strike, Jan 01 '21 at 18:34
Yes, its all pushed and committed, I even tried reinstalling all the packages, still the same issue EDIT: I dont have a gitignore on node_modules, might try doing that — BackspaceRGB, Jan 01 '21 at 18:46
Okay, that's likely the problem. Your `node_modules/` (probably) shouldn't be tracked at all. Let Heroku install dependencies itself. `git rm -r --cached node_modules/`, add `node_modules` to your `.gitignore`, then commit, and push again. — ChrisGPT was on strike, Jan 01 '21 at 18:51
This could also be a Node.js version mismatch. What version of Node.js are you developing with locally? [Add that to your `package.json`'s `engines`](https://stackoverflow.com/a/56562466/354577). — ChrisGPT was on strike, Jan 01 '21 at 18:54
Does this answer your question? [Heroku build failing on dependency install](https://stackoverflow.com/questions/62599213/heroku-build-failing-on-dependency-install) — ChrisGPT was on strike, Jan 01 '21 at 18:54
I added the ```.gitignore``` file, added ```node_modules``` to it, still says Build Failed. Am I doing something wrong? — BackspaceRGB, Jan 01 '21 at 18:55
The issues is that when I did ```node --version```, I get 15.0.1, but from the other topic it seems like that version doesnt work, so I did ```14.14.0``` in engines, still Build Failed EDIT: I put 15.0.1 in engines, app deploys, bot doesnt go online — BackspaceRGB, Jan 01 '21 at 19:00
Your "bot doesn't go online" issue is a completely different issue. Please don't ask new questions in the comments. — ChrisGPT was on strike, Jan 01 '21 at 19:04
