一、报错现象：
npm WARN registry Unexpected warning for https://registry.npmjs.org/: Miscellaneous Warning ETIMEDOUT: request to https://registry.npmjs.org/vue failed, reason: connect ETIMEDOUT 104.16.23.35:443

二、切换成淘宝镜像
npm config set registry https://registry.npm.taobao.org
重新安装npm i
request to httpsregistry.npm.taobao.org failed, reason certificate has expired的解决方案,
三、借鉴方案
3.1 查看当前的npm镜像设置：npm config list
3.2 清空缓存：npm cache clean --force
3.3 然后修改镜像即可：npm config set registry https://registry.npmjs.org/
3.4 再次运行： npm config list，查看 registry 已经被更改为默认的 npm 公共镜像地址。
四、可以正常使用npm啦～
