Webpack sass-loader with bootstrap

Question

I have just got my head into webpack but it has now thrown a fit when i try to include bootstrap-sass from the index.scss file.

This webpack conf works great and outputs a .css file to css/stylehseet.css

'use strict';

var path = require('path');
var ExtractTextPlugin = require('extract-text-webpack-plugin');

module.exports = {
    entry: {
        stylesheet: path.resolve(__dirname, 'scss/index.scss')
    },
    output: {
        path: path.resolve(__dirname),
        filename: 'bundle.bootstrap-sass.js'
    },
    module: {
        loaders: [
            {
                test: /\.scss$/,
                loader: ExtractTextPlugin.extract(
                    'style', // backup loader when not building .css file
                    'css!sass' // loaders to preprocess CSS
                )
            }
        ]
    },
    plugins: [
        new ExtractTextPlugin('css/[name].css')
    ],
    resolve: {
        modulesDirectories: [
            './node_modules'
        ]
    }
};

The problem is, in the index.scss I have to include bootstrap-sass. index.scss, which according to the https://www.npmjs.com/package/sass-loader#imports you add a ~ and webpack should then resolve it all:

$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import "~bootstrap-sass/assets/stylesheets/bootstrap";

Problem is in my attempts it isn't :/. I get the output:

Webpack is fairly powerful but it does take you round the houses to get going... This is my package.json file

{
  "name": "webpack-demo",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "John Carmichael",
  "license": "ISC",
  "dependencies": {
    "bootstrap-sass": "^3.3.6"
  },
  "devDependencies": {
    "css-loader": "^0.25.0",
    "extract-text-webpack-plugin": "latest",
    "node-sass": "^3.11.2",
    "sass-loader": "^4.0.2",
    "style-loader": "^0.13.1",
    "webpack": "^1.13.3"
  }
}

Is there something minor I am missing that anyone can spot :) ?

You may need an appropriate loader to handle this file type.

There's your problem.

The compliler is trying to load an .eot font file, but it doesn't know what to do with it, because you have not used an appropriate loader.

First, installl the file-loader and the url-loader in your dev dependencies, like so: npm install file-loader url-loader -D

Then, add these in your loaders

{
    test: /\.(woff|woff2)(\?v=\d+\.\d+\.\d+)?$/,
    loader: 'url-loader?limit=10000&mimetype=application/font-woff'
},
{
    test: /\.ttf(\?v=\d+\.\d+\.\d+)?$/,
    loader: 'url-loader?limit=10000&mimetype=application/octet-stream'
},
{
    test: /\.eot(\?v=\d+\.\d+\.\d+)?$/,
    loader: 'file-loader'
},

This way you will be able to load most types of fonts
