场景：
在执行npm install时提示npm WARN deprecated core-js@2.6.12，导致安装不了
提示的意思是：版本低不再维护了，让升级upgrade your dependencies to the actual version of core-js.
npm WARN deprecated core-js@2.6.12: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues.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.
解决方法：
npm i core-js
