执行npm install命令出错问题

\1. npm ERR! code E404 npm ERR! 404 Not Found - GET https://registry.npmjs.com/@mlamp%2Fuser-info-dropdown - Not found

是看到这个博主说的解决方案才解决的→https://blog.csdn.net/weixin_42677762/article/details/112556234

原因是npm源指向的问题，须执行以下命令：

npm config set registry https://registry.npmjs.org/

然后就可以正常安装了

\2. 报错如下：
