webpack - 如何将 vue 文件样式提取到一个单独的 style.css 文件中

Question

我正在使用 vue-loader，默认情况下，对于每个 vue 文件，您的 View 中都有一个样式标签，这不是一件好事，根据 vue-loader 文档，我可以做到这一点

https://vue-loader.vuejs.org/en/configurations/extract-css.html我的 webpack-config.js 文件

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

module.exports = {
  entry: './src/main.js',
  output: {
    path: path.resolve(__dirname, './dist'),
    publicPath: '/dist/',
    filename: 'build.js'
  },
  module: {
    rules: [
      {
        // this one extracts css files that imported to styles.css
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader' ,
          use: "css-loader"
        })
      },
      {
         // and this dude here extracts component's styles into styles.css
        test: /\.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
                  css: ExtractTextPlugin.extract({
          use: 'css-loader',
          fallback: 'vue-style-loader' 
        })
          }
        }
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /\.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      },
      {
       test: /\.(woff|woff2|eot|ttf|svg)(\?.*$|$)/,
       loader: 'url-loader?importLoaders=1&limit=100000'
     }
    ]
  },

      plugins: [
    new ExtractTextPlugin("styles.css"),
  ],
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    }
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
}

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
    })
  ])
}

但是这段代码根本不起作用，行为是一样的。

但是这样更好

 less: ExtractTextPlugin.extract({
              loader: 'css-loader!less-loader?indentedSyntax',
              fallbackLoader: 'vue-style-loader',
            }),
