As suggested in logs. You have to delete the below file:

C:\Users\AppData\Roaming\npm\ng.cmd

This is because you might have other version or some other program is using it and npm is not able to delete as it doesn't have the correct access right for the same.

Just delete the file and try again. (Note: Make sure you are not using it and if doing so then newer version should support the functionalities required)

I had the same issue once and fixed it by doing this, maybe it'll help you.

First open the cmd in Administrator mode ( Windows ) if its Linux just add sudo before the commands, then type the commands one by one

$ npm uninstall -g @angular/cli
$ npm cache clean
$ npm install -g @angular/cli

Let me know if it works :)

I had the same problem, deleting ng.cmd and also %appdata%\npm\node_modules\@angular\cli folder solved the problem.

Delete node Folder under program Files C:\Program Files (x86)
Delete npm and npm-cache folders C:\Users<user_name>\AppData\Roaming
Uninstall Node if installed from control panel
Install stable version of node from official website https://nodejs.org/en/
verify running below commands node -v and npm -v
Run npm install -g @angular/cli

Above Steps worked for me..
