报错1：查询版本

$ npm -v

npm WARN logfile could not create logs-dir: Error: EPERM: operation not permitted, mkdir ‘D:\Node.js\node_cache_logs’
npm WARN logfile could not be created: Error: ENOENT: no such file or directory, open ‘D:\Node.js\node_cache_logs\2022-09-12T01_48_51_164Z-debug-0.log’
npm WARN logfile could not create logs-dir: Error: EPERM: operation not permitted, mkdir ‘D:\Node.js\node_cache_logs’
npm WARN logfile could not be created: Error: ENOENT: no such file or directory, open ‘D:\Node.js\node_cache_logs\2022-09-12T01_48_52_183Z-debug-0.log’
8.15.0

解决方案：
Node.js安装文件夹>>右键-属性>>勾选完全控制，如果无法勾选，对目录下的node_cache与node_global文件夹进行勾选。

报错2：全局安装镜像

解决方案：
第一步，删除C:\Users目录下.npmrc文件；
第二步,输入命令npm cache clean --force；
重新安装cnpm，输入命令cnpm -v显示版本号即安装成功，如下：
