After installing the Nodejs, NPM's path has always been appdata, which means it's annoying, so try to modify it in the installation directory (d disk space is very large AH)
installation directory: D:\program Files\nodejs
First, create a new two folders (and Node_modules siblings) under Nodejs:
Node_global and Node_cache
Second, cmd settings (quotation marks must be):
NPM config set cache "D:\nodejs\node_cache"
NPM config set prefix "D:\nodejs\node_global"
Third, change the configuration file. NPMRC (D:\program files\nodejs\node_modules\npm):
Prefix=d:\program Files\nodejs\node_global
Cache=d:\program Files\nodejs\node_cache
Iv. whether the test is successful:
Success ~ ~ ~ the installation path is the one you just set
PS: There is no environment variable at the moment, you need to fill it later
