Push rejected, failed to compile Node.js app heroku

When I tried to push my nodejs app to heroku with git push heroku master, i got this:

Counting objects: 975, done.

Answer 1

Try setting a heroku-postbuild script to your package.json and make sure to include your engines.

"scripts": {
        "heroku-postbuild": "npm run build"
    },
"engines": {
        "npm": "5.6.0",
        "node": "8.10.0"
      }

I would try and avoid force pushing anything at all costs whether it be to github or heroku.
