Module not found for path with backslash

Hi, I stumbled on #428 which describes nearly my problem, except that I am already (I think?) specifying an absolute path for the resolve root…

Project structure:

webpack-test/
    src/
        greeting/
            greeting.js
            greeting.css
        app.js
    dist/
    node_modules/
    webpack.config.js

Import in greeting.js:

import 'greeting.css';

Error message:

ERROR in ./greeting/greeting.js
Module not found: Error: Cannot resolve module ‘greeting.css’ in C:\Users\Stijn\Documents\GitHub\webpack-test/src\greeting
@ ./greeting/greeting.js 15:0-23

The file does exist. In fact, if I copy-paste the path in the error message to a Windows Explorer window, it immediately takes me to the right folder and I see it right there.

Contents of my webpack.config.js:

module.exports = {
    context: __dirname + '/src',
    entry: {
        javascript: './app.js',
    },
    output: {
        filename: 'app.js', 
        path: __dirname + '/dist',
        publicPath: 'http://localhost:8090/assets'
    },
    module: {
        loaders: [
            {test: /\.js$/,  include: /src/, loaders: ['react-hot', 'babel-loader']},
            {test: /\.css$/, include: /src/, loaders: ['style-loader', 'css-loader']}
        ]
    },
    externals: {
        'react': 'React'
    },
    resolve: {
        extensions: ['', '.js', '.jsx', '.css']
    },
    resolveLoader: {
        root: __dirname + '/node_modules'
    }
}

I also tried with a relative import:

import './greeting.css';

But then I get 2 errors that look more difficult… 🙂

ERROR in ./greeting/greeting.css
Module not found: Error: Cannot resolve ‘file’ or ‘directory’ ./../../node_modules/css-loader/index.js > in C:\Users\Stijn\Documents\GitHub\webpack-test/src\greeting
@ ./greeting/greeting.css 4:14-82

ERROR in ./greeting/greeting.css
Module not found: Error: Cannot resolve ‘file’ or ‘directory’ ./../../node_modules/style-loader/addStyles.js in C:\Users\Stijn\Documents\GitHub\webpack-test/src\greeting
@ ./greeting/greeting.css 7:13-71

Any tips for webpack n00b?
