webpack, sass, react-css-modules - ReferenceError window is not defined - sass

Question

I'm using webpack and React with react-css-modules and scss files. When i try and build it gives me an error on every file that imports scss files -
ERROR in ./app/components/Buttons/Button.scss
Module build failed: ReferenceError: window is not defined
I have googled for a solid day and a half and have got no where! Please help!
Here's my webpack set up:
var webpack = require('webpack');
var PROD = (process.env.NODE_ENV === 'production');
var precss = require('precss');
var autoprefixer = require('autoprefixer');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var HTMLWebpackPluginConfig = new HtmlWebpackPlugin({
template: __dirname + '/app/index.html',
filename: 'index.html',
inject: 'body'
});
module.exports = {
entry: [
'./app/index.jsx'
],
output: {
path: __dirname + '/dist',
filename: PROD ? 'bundle.min.js' : 'bundle.js'
},
watchOptions: {
poll: true
},
module: {
preLoaders: [
{
test: /\.jsx$|\.js$/,
loader: 'eslint-loader',
include: __dirname + '/assets',
exclude: /bundle\.js$/
}
],
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loader: "babel-loader",
query: {
presets: ['es2015', 'react']
}
},
{
test: /\.scss$/,
loader: ExtractTextPlugin.extract('style', ['style!css?sourceMap&localIdentName=[local]___[hash:base64:5]!resolve-url!sass?outputStyle=expanded'])
}
]
},
postcss: [autoprefixer({ browsers: ['last 2 versions'] })],
resolve: {
extensions: ['', '.js', '.jsx']
},
plugins: PROD ? [
new webpack.optimize.UglifyJsPlugin({
compress: { warnings: false }
})
] : [
HTMLWebpackPluginConfig,
new ExtractTextPlugin("styles.css", {
allChunks: true
})
]
};
Thanks in advance!

Answer 1

This question keeps popping up when I tried to resolve the same error for Webpack 2, scss, extracttextplugin, and react. The following worked for me.
{
test:/\.scss$/,
use:ExtractTextPlugin.extract({fallback:"style-loader",use:["css-loader","sass-loader"]}),
include:path.join(__dirname,"client/src"),
},
Hope this helps.

I think you have to change it to this, the second parameter goes as a string instead of array. Also removed the repeated use of the style loader.
loader: ExtractTextPlugin.extract('style', 'css?sourceMap&localIdentName=[local]___[hash:base64:5]!resolve-url!sass?outputStyle=expanded')
