How to run node-canvas on heroku?

Question

I've created a discord bot with node.js that uses a npm called canvas which is running version 2.6.1 but when I wen't to push my files to github and deploy I keep getting faced with errors. If this helps I'm running one buildpack which is the default node.js one.

I've tried using a buildpack that you can find here: https://github.com/Automattic/node-canvas/wiki/Installation:-Heroku but that doesn't work.

       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
         https://devcenter.heroku.com/articles/node-best-practices#only-git-the-important-bits
       
       - Node version not specified in package.json

       Love,
       Heroku

Any reason to this and how I can fix this? I've been struggling on this for around an hour or so now.
