Configuration environment variable and view node.js and npm version
Npm path configuration and path caching global cache at installation module
For example, when performing because npm install webpack -g command and other global installed, the default with modules installed in C: \ Users \ username \ AppData \ npm and npm_cache under Roaming path management is not convenient and takes up C drive space. So here you configure a custom installation global directory module, and two new folders node_global node_cache in node.js installation directory,
Then execute the following two commands in cmd command:
npm config set prefix "D:\Program Files\nodejs\node_global"
npm config set cache "D:\Program Files\nodejs\node_cache"
execution succeed. Then in the environment variable - New> a system variable named variable "NODE_PATH", is "D: \ nodejs \ node_modules", as shown below:
Last edited user variables in the Path, will be before the corresponding npm path C: \ User \ user \ AppData \ Roaming \ npm read: D: \ nodejs \ node_global
Implementation of npm install webpack -g command in cmd then you can see two custom file folders in effect after successful installation:
