  I have a fail to compile Webpack, but I do not know how resolve it. 
  I use postcss. </p>

      test: /\.css$/,
      use: [
        'vue-style-loader',
        { loader: 'css-loader', options: { importLoaders: 1 } },
        'postcss-loader'
      ],
    },      {
      test: /\.vue$/,
      loader: 'vue-loader',
      options: {
        postcss: [require('postcss-cssnext')()],
        loaders: {
        }
        // other vue-loader options go here
      }
    },
  </code></pre>
  
  <p>And it is the fail     </p>
  
  <pre><code>   ./node_modules/vue-double-list/index.js
     Module parse failed: Unexpected token (1:20)
     You may need an appropriate loader to handle this file type.
     | export default from './dist/vue-double-list.common'
     | export * from './dist/vue-double-list.common'
     | import './dist/vue-double-list.css'
     @ ./src/main.js 11:0-41
     @ multi (webpack)-dev-server/client?http://localhost:8080 webpack/hot/dev- 
     server ./src/main.js
