如，我给一个项目用yarn装依赖，这时候报错：
yarn install v1.22.21 info No lockfile found. [1/4] Resolving packages... error Error: certificate has expired at TLSSocket.onConnectSecure (node:_tls_wrap:1539:34) at TLSSocket.emit (node:events:513:28) at TLSSocket._finishInit (node:_tls_wrap:953:8) at TLSWrap.ssl.onhandshakedone (node:_tls_wrap:734:12) info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.
关键信息：error Error: certificate has expired（错误错误：证书已过期）
好了，回想一下我给yarn用的是淘宝的镜像源链接：https://registry.npm.taobao.org
然后我在浏览器打开该链接，发现该链接的证书过期了
抱着试一试的态度，把https改成了http，再次切换镜像源：
yarn config set registry http://registry.npm.taobao.org
然后，重新在项目中用yarn拉取项目，就可以了。
