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