报错信息：

C:\Users\xxx>npm install yarn -g
npm ERR! code CERT_HAS_EXPIRED
npm ERR! errno CERT_HAS_EXPIRED
npm ERR! request to https://registry.npm.taobao.org/yarn failed, reason: certificate has expired

其原因是官方修改了淘宝镜像源的地址，不管通过npm安装什么都会导致报错

解决办法：

重新安装新的淘宝镜像源：

npm config set registry https://registry.npmmirror.com

安装后检查一下：

npm config get registry

再通过npm安装就不会执行报错了。
