Sass加载器不在webpack中工作-Sassloadernotworkinginwebpack

I am trying to get *.scss files to be supported in my webpack configuration but I keep getting the following error when I run the webpack build command:

我试图在我的webpack配置中获得* .scss文件，但是当我运行webpack build命令时，我一直收到以下错误：

ERROR in ./~/css-loader!./~/sass-loader!./app/styles.scss

I can't for the life of me figure out why. It's a very basic setup.

我不能为我的生活找出原因。这是一个非常基本的设置。

I have created a dropbox share with the bare minimum illustrating this: https://www.dropbox.com/s/quobq29ngr38mhx/webpack.sass.test.zip?dl=0

我创建了一个Dropbox共享，最低限度说明了这一点：https：//www.dropbox.com/s/quobq29ngr38mhx/webpack.sass.test.zip？dl = 0

Unzip this then run:

解压缩然后运行：

npm install
webpack

Here is my webpack.config.js file:

这是我的webpack.config.js文件：

var path = require('path')
var webpack = require('webpack')

module.exports = {
  devtool: 'eval',
  entry: [
    './app'
  ],
  output: {
    path: path.join(__dirname, 'dist'),
    filename: 'index.js',
    publicPath: '/dist/'
  },
  plugins: [
    new webpack.NoErrorsPlugin()
  ],
  resolve: {
    extensions: ['', '.js']
  },
  module: {
    loaders: [{
      test: /\.scss$/,
      loader: 'style-loader!css-loader!sass-loader'
    }]
  }
}

And the index.js entry file:

和index.js条目文件：

require('./styles.scss');

alert('foo bar baz');

And the styles.scss file:

和styles.scss文件：

body {
  background-color: #000;
}

It appears to follow the recommendations of the sass-loader documentation site, but I can't get it to run.

它似乎遵循sass-loader文档站点的建议，但我无法运行它。

var path = require('path')
var webpack = require('webpack')

module.exports = {

  entry: [
    './app'

  output: {
    path: path.join(__dirname, 'dist'),

  },
  module: {
    loaders: [{
      test: /\.scss$/,
      loader: 'style!css!sass?sourceMap'
    }]
  }
}

if(map && typeof map !== "string") {
    map = JSON.stringify(map);
