vue项目中引用样式文件出现： This dependency was not found

vue项目中引用样式文件出现：

This dependency was not found:
* common/stylus/index.styl in ./src/main.js
To install it, you can run: npm install --save common/stylus/index.styl

解决方法：

在 build\webpack.base.conf.js中
resolve添加 'common': resolve('src/common')，如下：
resolve: {
  extensions: ['.js', '.vue', '.json'],
  alias: {
    'vue$': 'vue/dist/vue.esm.js',
    '@': resolve('src'),
    'common': resolve('src/common')//此处为添加内容
  }
}, 

如果是下面导致的

These dependencies were not found: 
* !style!css!./bootstrap/css/bootstrap.css in ./src/main.js  
引用文件的去掉!style!css!去掉试试
