报错情况：
[2/4] Fetching 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. StackOver同样有这样的问题
解决方法：
①禁用SSL证书验证
yarn config set strict-ssl false②重新设置npm镜像源（二选一）
npm config set registry http://registry.cnpmjs.org npm config set registry http://registry.npm.taobao.org
