The app runs fine after an \'npm start\' in windows, but when I pull from github into Heroku I just get an error.

package.json:

Heroku doesnt install devdependencies by default:. https://devcenter.heroku.com/articles/nodejs-support. Either set your react-scripts module to always install or turn off production mode on Heroku.
