Windows在安装cnpm时出现如下错误

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! 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.

网上的方法都试过了，不可用，我安装的nodejs版本是v14.21.3，直接执行npm i -g cnpm会出现如上错误，可尝试降低安装版本

npm i -g cnpm@8目前最新版本是9.x，尝试安装npm 8.x版本，如果不行继续降@7 @6等
