Cant resolve module 'babel' when running dist - reactjs

Question

I´ve built my project upon the generator-react-webpack. Now I am trying to deploy my react app to Heroku. In the process of Building dependencies I get an error:
npm run copy & webpack --env=dist
remote:
remote: Hash: 82c8f499a3f6822a3522
remote: Version: webpack 1.13.3
remote: Time: 73ms
remote:
remote: ERROR in Entry module not found: Error: Cannot resolve module 'babel' in /tmp/build_a9e8f64bdab19b2486d922d4ba0f3d83
There seems to be something weird with the loader. I´ve tried to include 'babel' in dependencies, and also tried to replace it with 'babel-core' and it did not work.
I´m super frustrated with this problem and would appreciate it alot if someone could help me. Thanks!

Answer 1

From https://github.com/mxstbr/react-boilerplate/issues/914
"Make sure you set NPM_CONFIG_PRODUCTION=false on heroku. Without this devDependencies won't be installed. Which are needed for this boilerplate to build.
If you have heroku cli installed you can
heroku config:set NPM_CONFIG_PRODUCTION=false --app your-app-name
else go to the settings tab on your app and add in Config Variables"
This fixed it!

Can you change your entry from your dist.js file to this:
entry: [
'babel-polyfill',
path.join(__dirname, '../src/index')
],
