What are these - environment variables, I want portable?

Question

Node.js

I installed OpenServer on a portable sdd, and I also put all the necessary tools nearby.
For example, the installation of NODE.js is in the path F:\OpenServe\modules\nodejs.
In the OpenServer settings (F:\OpenServe\userdata\config) I write my path`s.

1. Am I understanding correctly, if I remove pach C:\Users\Git\AppData\Roaming\npm from environment variables (img), then system CMD won't see NPM?
   
2. What is this path for, what is C:\Users\Git\AppData\Roaming\npm stored there?
   

I want to use node, only in OServer, portable.

Answer 1

That's right, if you remove the paths from the system environment variables, then not a single application of the system will know about these paths, including the command processor.
The path %USERPROFILE%\AppData\Roaming\npm contains the executables of installed npm packages that provide some packages. To change this path, you need to use npmrc on the Node.js installation path. More details - https://docs.npmjs.com/cli/v7/configuring-npm/folders
Portable installation implies no connection with the system environment, and the right solution is to use the environment and the OSPanel shell, of course.
