Npm error while trying to create angular and React Project

What I Wanted to Do

I wanted to create and run angular2+ react project in my PC.

I normally did the necessary step to using npm like first i install node js version 8.x then i installed angular cli then i tried to create an application but it was throwing error. similarly i did with create-react-app its got installed but again while creating a project its not getting created. instead the previous created angular project is running fine. Attaching the image for reference.

What Happened Instead

Reproduction Steps
