在Vue.js中使用Stylus预处理器

1.安装stylus和loader

$npm install stylus stylus-loader --save-dev

2.webpack配置（红色部分）

module: {
    rules: [
      {
        test: /.css$/,
        use: [
          'vue-style-loader',
          'css-loader',
        ],
      },      {
        test: /.vue$/,
        loader: 'vue-loader',
        options: {
          loaders: {
          }
          // other vue-loader options go here
        }
      },
      {
        test: /.js$/,
        loader: 'babel-loader',
        exclude: /node_modules/
      },
      {
        test: /.(png|jpg|gif|svg)$/,
        loader: 'file-loader',
        options: {
          name: '[name].[ext]?[hash]'
        }
      },
      {
        test:/.styl$/,                             //add(stylus)
        loader: 'style-loader!css-loader!stylus-loader'
      }
    ]
  },
  resolve: {
    alias: {
      'vue$': 'vue/dist/vue.esm.js'
    },
    extensions: ['*', '.js', '.vue', '.json','.styl']         //add(stylus)
  },
  devServer: {
    historyApiFallback: true,
    noInfo: true,
    overlay: true
  },
  performance: {
    hints: false
  },
  devtool: '#eval-source-map'
}
