webapck编译打包stylus文件

先安装css-loader、stylus、stylus-loader

npm install --save-dev css-loader

npm install --save-dev stylus

npm install --save-dev stylus-loader

webpack.config.js里的配置

module:{
    rules:[
      {
        test: /\.css$/,
        use: extractTextPlugin.extract({
          fallback: "style-loader",
          use: [{loader:"css-loader",options:{importLoaders:1}},'postcss-loader']
        })
      },     
      {
        test: /\.styl(us)?$/,  //注意这块
        use: extractTextPlugin.extract({
          use: [{
            loader: "css-loader"
          }, {
            loader: "stylus-loader"
          }],
          // use style-loader in development
          fallback: "style-loader"
        })
      }
    ]
  }
