javascript - vue單一頁面應用程式怎麼把樣式抽取到一個獨立檔案？

Question

問題是這樣的現在在做一個SAP應用，webpack配置了抽取檔案出來。樣式既沒有抽取成一個檔案也沒有被webpack打包到js裡面，而是在頁面上產生style標籤了。求大神指教。
用的是vue2，webpack2
webpack設定：

var path = require('path')
var vuxLoader = require("vux-loader");
var webpack = require('webpack');
var ExtractTextPlugin = require("extract-text-webpack-plugin");



const webpackConfig = {

  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    rules: [
      {
          test: /\.vue$/,
          loader: 'vue-loader',
          options: {
            loaders: {
              'scss': 'vue-style-loader!css-loader!sass-loader',
              'sass': 'vue-style-loader!css-loader!sass-loader?indentedSyntax'
            }
          }
      },
      {
          test: /\.js$/,
          loader: 'babel-loader',
          exclude: /node_modules/
      },
      {   test: /iview.src.*?js$/, loader: 'babel' },
      {
          test: /\.css$/,
          use:new ExtractTextPlugin({
              filename:'build.css',
              ignoreOrder:true
          }).extract({
            use:{
              loader:'css-loader',
              options:{
                modules:true
              }
            },
            fallback:'style-loader'
          })
      },
      {
          test: /\.less$/,
          loader:'style-loader!css-loader!less-loader'
      },
      {
          test: /\.(eot|woff|woff2|ttf)$/,
          loader: 'url-loader?limit=30000&name=[name]-[hash].[ext]'
      },
      {
          test: /\.(png|jpg|gif|svg)$/,
          loader: 'file-loader',
          options: {
            name: '[name].[ext]?[hash]'
          }
      }
    ]
  },
  vue:{
    loaders :{
      css: ExtractTextPlugin.extract({fallback:'style-loader', use:'css-loader'})
    }
  },
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['.js', '.vue', '.json']
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
};

module.exports = vuxLoader.merge(webpackConfig, {plugins:['vux-ui']});

if (process.env.NODE_ENV === 'production') {
  module.exports.devtool = '#source-map'
  // http://vue-loader.vuejs.org/en/workflow/production.html
  module.exports.plugins = (module.exports.plugins || []).concat([
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: '"production"'
      }
    }),
    new webpack.optimize.UglifyJsPlugin({
      sourceMap: true,
      compress: {
        warnings: false
      }
    }),
    new webpack.LoaderOptionsPlugin({
      minimize: true
    })
  ])
}

package.json:

{
  "name": "blog",
  "description": "leung blog mobile",
  "version": "1.0.0",
  "author": "leung",
  "private": true,
  "scripts": {

  },

    "vux-loader": "^1.0.57",
    "webpack": "^2.2.0",
    "webpack-dev-server": "^2.2.0"
  }
}

如果我把這段程式碼註解了就沒報錯了 T_T

vue:{
    loaders :{
      css: ExtractTextPlugin.extract({fallback:'style-loader', use:'css-loader'})
    }
  },

搞不懂，求賜教

下面這個範例給你參考，希望對你有幫助

const path = require('path');
const webpack = require('webpack');
const ExtractTextPlugin = require("extract-text-webpack-plugin");
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  entry: {
    main: './src/index.js',
    vendor: ['vue', 'vue-router','vuex']
  },
  output: {
    path: path.resolve(__dirname, 'dist'),
    publicPath: '',
    filename: 'js/build.js'
  },
  module: {
    rules: [{
        test: /\.vue$/,
        use: [{
          loader: 'vue-loader',
          options: {
            loaders: {
              css: ExtractTextPlugin.extract({
