Module build failed: Error: "extract-text-webpack-plugin" loader is used without the corresponding plugin

Thank you for an awesome template. I have run into this error with Windows 10, node 7.5.0 and npm 4.1.2. This error is with the boilerplate code unmodified and running with NODE_ENV=production. There is no error with NODE_ENV=testing or development.

I found out that webpack.prod.conf was not loaded when NODE_ENV === 'production'. I’ve solved it as followed in dev-server.js :

var webpackConfig = process.env.NODE_ENV === 'testing' || 'production'
  ? require('./webpack.prod.conf')
  : require('./webpack.dev.conf')

Problem fixed for me too: NODE_ENV=development. I added it in ‘dev’ script (for windows): "dev": "cross-env NODE_ENV=development node build/dev-server.js"
