记录一下 报错：deprecated core-js@2.6.12: core-js@小于3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js. 顾名思义，core js@❤️.23.3不再维护，由于问题数量众多，不建议使用。需要升级core-js的版本 使用如下命令更新版本：

npm i core-js
