【报错】npm ERR! ERESOLVE could not resolve、certificate has expired

前情提要

使用npm淘宝镜像 https://registry.npm.taobao.org

年前创建的vue3项目npm install 完后没有使用ui写了点杂七杂八的东西，年后看到一篇文章有点兴趣，掏出来准备试一下，本打算安装element-plus 写起来方便点npm install element-plus --save ，结果就运行后就报错

npm ERR! code ERESOLVE

npm ERR! 

看这一堆眼花缭乱的，其实最有用的就是后几行，让我们在原本命令上增加 --force or --legacy-peer-deps

npm ERR! Fix the upstream dependency conflict, or retry
npm ERR! this command with --force or --legacy-peer-deps
npm ERR! to accept an incorrect (and potentially broken) dependency resolution.

也就是npm install element-plus --save --force 跑起来又又报错了=.=，好好好，看看报错信息

上面都是WARN不用管，重点看ERR，他说xxx https://registry.npm.taobao.org/element-plus failed(失败)

这个地址很眼熟啊，npm taobao这不就是淘宝镜像吗，reason:原因 certificate has expired 证书已过期，好家伙，搞了半天淘宝镜像过期了

npm ERR! code CERT_HAS_EXPIRED
npm ERR! errno CERT_HAS_EXPIRED
npm ERR! request to https://registry.npm.taobao.org/element-plus failed, reason: certificate has expired

解决

找到根源，就好解决了， 切换npm镜像源

// 先清除缓存
npm cache clean --force
npm config set registry npm镜像源

开始百度"淘宝镜像过期"，找到一篇一个月前热气腾腾的救命文章 npm 淘宝镜像正式到期，赶紧更新！

换源

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

重新执行，安装成功🏅

npm install element-plus --save --force
