I can't install Angular CLI properly - node.js

Question

I have been searching for solutions, but I still can't install Angular CLI on my computer. I always get errors. What seems to be the problem? Help.
I already tried running the cmd line as an administrator, but it still does not work. I also tried clearing the npm cache.
My node.js is in the latest version: Node.js v15.5.1.
This is the console log error:
npm ERR! code EPERM
npm ERR! syscall rename
npm ERR! path C:\Program Files (x86)\Nodist\bin\node_modules\#angular\cli

I think you should do the following; If you are on windows try to run below command using admin access and on linux based systems use sudo:
npm uninstall -g #angular/cli
npm cache clean --force
These commands will actually remove the previous installations and then check:
ng --version --> it should throw an error
Reinstall the angular package:
npm install -g #angular/cli
Then check your version again:
ng --version
To add one more thing, you can use multiple versions of node. So if you are using linux based computer. You can install nvm and you can install multiple versions of node: https://github.com/nvm-sh/nvm -- and for windows, you can use this : https://github.com/coreybutler/nvm-windows
This way you can check what versions of node are causing an issue, or it is actually a problem with angular installation.
