node.js - windows10下的npm全局路径的复原或者将npm彻底删除？

Question

windows10系统，之前嫌每次全局安装和查询路径都不匹配，于是照着网上的教程改了一下：
1.把npmrc这个文件里的prefix和cache改成了自己的想要的路径：指向了在E盘新建了node-cache和node-global的两个文件夹
2.在git bash中使用npm config set 命令将prefix和cache路径又改了一遍（与1中相同）
3.在系统的环境变量中添加了NODE_PATH文件夹所在路径
然后现在无论是全局还是本地都不好使了，我再全局安装gulp然后在本地文件夹也安装了，但是在git bash里面显示bash:gulp:command not found，单纯卸载npm和nodejs再重新安装没有效果，npm root -g什么的路径没有改变，其他的路径也还会保留之前的设置，想请问一下如何彻底卸载或者有什么解决办法吗？
感谢回复。。折腾了好久也不见效果。。。

Answer 1

After adding NODE_PATH to the environment variable, the Path should also be changed to "D:nodejsnode_global", so that your new directory should be usable

But the directory cannot be deleted, please ask

Answer 2

Is the problem solved? After I installed npm, I also set up cache and global, and also specified install -g during installation. But after the installation is completed, it is always in the user directory of the C drive, not in the specified directory. And for example, if you install express, you will get the message "cannot find modules" when using express

Answer 3

Just install nvm-windows
