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:

npm cache clean --force
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

You need to delete package-lock.json and try installing again.
