vue项目使用的是sass打包报错

vue项目中，我使用的是sass、sass-loader，但是打包的时候报错，sass版本是最新的

(因为node-sass被官方废弃了，不建议使用，所以我改用的sass)
我已经使用过sass-migrator division **/*.scss命令，并且在vue.config.js配置了css,具体如下：

    //  loaderOptions: {//放置element 图标乱码
    //   sass: {
    //     implementation: require('sass'),
    //     sassOptions: {
    //       // 生效代码
    //       outputStyle: 'expanded'
    //     }
    //   }
    // },

报错信息：
```javascript
