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)
    }
