Issue with npm after reinstalling node.js

I recently reinstalled node.js (latest version, 9.8.0) on my computer (running windows 10) as it started to glitch out.

The problem is, now npm doesn't work. For example, upon entering npm in cmd, I get the error:

Error: EPERM: operation not permitted, mkdir 'C:\Program Files (x86)\Nodist'
TypeError: Cannot read property 'get' of undefined

The node command works fine, though. Why would this happen?

Edit: I have tried reverting to the recommended Node.js version (8.10.0), but I am getting the same issues.

To fix this in Windows, create a directory junction to your users folder that didn't have a space in it. You can run a command like this in an administrative powershell:

cmd /c mklink /J "C:\Users\myname" "C:\Users\My Name"

You can then use this junction as if it were your real user directory:

npm config set cache C:\Users\myname\AppData\Roaming\npm-cache

npm config set prefix C:\Users\myname\AppData\Roaming\npm

(the above should update your user .npmrc file)

I had a similar problem a while ago. Try navigating to the file named .npmrc, in C:\Users\%UserName%, and deleting it.

This maybe related to the NPM cache that needs to be cleaned you can do it using: 

    npm cache clean

Let me know if it helped....
