npm 报错 EPERM: operation not permitted

昨天从拉了个前端项目下来，用IDEA打开，例行npm install，安装到一般报错EPERM: operation not permitted

按网上的删除package-lock.json后，情况依旧

以为是管理员权限问题，于是win + x再按a调出powershell，进入项目目录，执行npm install，报zlib: unexpected end of file，于是执行npm cache clean -force ，报错

npm ERR! The operation was rejected by your operating system.
npm ERR! It's possible that the file was already in use (by a text editor or antivirus),
npm ERR! or that you lack permissions to access it.
npm ERR!
npm ERR! If you believe this might be a permissions issue, please double-check the
npm ERR! permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator (though this is not recommended).

那我直接打开资源管理器，删除这个文件不就好了，可是删不掉啊，Access is denied，查看文件属性-安全-高级，Unable to display current owner. 连文件所属用户都看不到啊！

后来我甚至登录Administrator账户，都删不了

后来想了想，会不会是IDEA占用的问题呢，直接把IDEA关了，再npm cache clean -force，提示npm-cache文件夹busy，命令提示行退出该目录，再执行一次，竟然好了？！

然后npm install，竟然一切正常？！跟我闹着玩呢？
