vue项目打包后element-ui的icon显示小方框

vue项目打包后element-ui的icon显示小方框，经检查是.iconfont的css中font-family: iconfont!important 导致

你在打包的时候，在build的文件夹里的utils.js的文件里面添加
publicPath: '../../'
```publicPath: '../../'

```function generateLoaders (loader, loaderOptions) {
    const loaders = options.usePostCSS ? [cssLoader, postcssLoader] : [cssLoader,px2remLoader]

    if (loader) {
      loaders.push({
        loader: loader + '-loader',
        options: Object.assign({}, loaderOptions, {
          sourceMap: options.sourceMap
        })
      })
    }

    // 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)
    }
  }
