• About Environment Variables

If you can not use after the installation, you need to manually set it.

    

    

    If you do not use, adding an environment variable to point node_global folder NODE_PATH

    

 

Fourth, the installation was encountered pit

Remember to install five or six times, first installed version 12.0, version 11.0 is installed after the last version 10.0 is installed. Because when installed is the latest nodejs, there are locally cached files after installation, installed after lead node can be used, but not with npm, the solution is to delete cache files.

• 如果用不成npm可以试试删除C:\Users\Admin下的.npmrc或者.node_repl_history，这两个文件有哪一个就删除哪一个。其中第一个为低版本的缓存文件、第二个为新版本的缓存文件。

 

• 如果还不行，在试试删除C:\Users\Admin\AppData\Roaming的这两个文件夹，然后卸载nodejs，重启电脑在安装一遍nodejs。
