yarn install 的时候报了错误
error An unexpected error o***urred: "https://registry.npmmirror.***/moment: tunneling socket could not be established, cause=socket hang up".
解决方法
查看镜像
npm config get registry //查看
yarn config get registry
// https://registry.npm.taobao.org/
切换淘宝镜像
npm config set registry https://registry.npm.taobao.org
yarn config set registry https://registry.npm.taobao.org
我换了原来的镜像
npm config set registry http://registry.npmjs.org
yarn config set registry https://registry.yarnpkg.***
yarn 不行就换npm，确保都换了，然后这个报错就可以解决了
如果还不行的，检查你的代理地址是否正确，是否防火墙影响
