引起原因
看提示，缺少core-js包或者core-js包版本不对：
To install them, you can run: npm install --save core-js/modules/es.array.push.js core-js/modules/es.array.unshift.js core-js/modules/es.error.cause.js core-js/modules/es.object.proto.js
直接执行命令依旧报错：
提示没有core-js目录
解决办法
安装core-js模块
先删除node_modules 中的core-js文件夹，然后重新安装高版本
安装报错的插件
cnpm install --save core-js@3.22.8
安装其他
cnpm i
打包
cnpm run build:prod
