记录报错之npm WARN deprecated core-js@3.6.5: core-js@＜3.23.3 is no longer maintained and not recommended for u

当前core-js@2已经放弃维护了，所以要装3以上的版本。

启动的时候出现的问题为

This dependency was not found:

core-js/modules/es.error.cause.js in ./node_modules/@babel/runtime/helpers/createForOfIteratorHelper.js, ./src/directive/permission/hasPermi.js and 5 others

To install it, you can run: npm install --save core-js/modules/es.error.cause.js

解决方法：
1、先删除 node_modules 依赖
npm rm -rf node_modules

 

2、首先安装 报错的插件
npm install --save core-js

3、最后再 npm install 或者 yarn install
npm install或者yarn install

4、最后 npm run dev 运行启动
npm run dev
