Git bash 全局安装Vuepress时【npm install -g vuepress】报的一个npm WARN

解决方案：

npm install --save  -g core-js@^3

Administrator@GuoXinYu MINGW64 /d
$ npm install --save  -g core-js@^3

> node -e "try{require('./postinstall')}catch(e){}"

+ core-js@3.6.4

网上有些人写的方案不好，他们没有加-g，这样你安装的node_modules就直接被装在当前目录了，直接装在了D盘下，很不好看。

应该开启全局安装，这样方便整理一点。如图：

npm install --save  -g core-js@^3
