2、原因
没有管理员权限，无法在node_global和node_cache两个文件夹下进行一些必要的操作
3、解决
直接修改node_global和node_cache文件夹的权限：
存放全局模块(node_global)和缓存文件(node_cache)。
给这2个文件夹设置权限，右键文件夹->属性->安全tab，选择编辑，将没有打钩的位置全部打上钩（即将其它用户的权限设置为与管理员相同），应用即可。
设置新的路径：window+R+cmd 进入终端，通过npm配置命令npm config set prefix 和 npm config set cache来分别指定新的全局模块安装路径和缓存路径；说明：
prefix = 创建的node_global文件夹所在路径
cache = 创建的node_cache文件夹所在路径
npm config set prefix "D:\node-v20.16.0-x64\node_global"
npm config set cache "D:\node-v20.16.0-x64\node_cache"
