You do not need to uninstall or install anything. Just

npm cache clean --force

and then

npm install

will do.

In the folder where you have tried to create project setup, just run these 2 commands:

  1. npm cache clean --force
  2. npm install

Afterwards, run the commands needed to setup your project directory.

This issue was solved by going to C:\Users\USERNAME\AppData\Roaming\npm-cache and deleting its contents manually , then later running cmd as Administrator and running npm install

open the cmd in adminstator mode then run the following commands in order specify

npm cache clean --force 
go in the c:/user/user_name/AppData/Roaming/npm     => clean this folder 
npm install -g @angular/cli
ng new project_name

Hope it will work.
