排查解决过程：
1、确认.npmrc配置文件中设置的源地址不是私有库地址。
npm config get registry
设置为阿里源：npm config set registry https://registry.npmmirror.com
2、查看日志（此方法解决）
查看/usr/local/www/.npm/_logs/2024-10-28T10_39_48_122Z-debug-0.log 日志文件
确认异常包具体报错原因，如果.npmrc文件中是公有库地址，异常报错为私有库地址，则说明有缓存。
解决：删除node_modules和package-lock.json ，重新执行npm install
