vue项目build后font-awesome不显示问题

解决办法：

修改build目录下的utils.js：添加 publicPath: '../../'

     // Extract CSS when that option is specified
     // (which is the case during production build)
     if (options.extract) {
       return ExtractTextPlugin.extract({
         use: loaders,
         fallback: 'vue-style-loader',
         publicPath: '../../'
       })
     } else {
       return ['vue-style-loader'].concat(loaders)
     }
