运行vue-element-admin的时候报如上错误
应该是：
npm install --registry=https://registry.npm.taobao.org执行的时候，出现错误

没有sass-loader和node-sass模块

解决方案

分别执行这两条命令：

1、npm install node-sass --save-dev
2、npm install sass-loader --save-dev

回到根目录
然后依次执行删除
node_modules package-lock.json文件夹

再依次执行以下代码
开启新的命令窗口

npm cache clear --force
npm install

npm run dev
