In my System Angular Version 17 was installed. I tried installing Angular 15. To achieve this I tried
- npm uninstall -g @angular/cli. Angular is successfully uinstalled.
- npm cache clean(this throws the error, it was suggesting to use --force).Screenshot added.

- Uninstall node(as I had latest node, i.e, 20).
- Downloaded node v18.10.0.
- npm i @angular/[email protected]. This is giving some warning and angular is not installed.
