Answer 1

I was faced this same problem . It is due to the issue with npm .

please run the following command in command Line

npm cache clean --force 

then run

create-react-app <project Name> 

If your problem still exist then switch from npm to yarn

run the following commands, it solved my problem

npm install -g yarn  yarn global add create-react-app  create-react-app <projectname> 

Answer 2

It looks like you need admin privileges to write some of the generated files. Can you create a terminal instance with administrator rights then reissue the command?

Answer 3

You probably had "create-react-app" running before, which was the problem in my case anyway. The way I solved this was using npm cache clean --force and ran create-react-app my-app again.
