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?

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.

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>

For me, i wasn't connected to the internet when i tried to run 'create-react-app', so i connected and tried it, it worked, i'm guessing it needed to install some packages from the internet.

I suspect npm has an issue. However, this was how I was able to resolve it

follow this steps, i assure you, you will get it resolved. It worked for me

1. npm install -g yarn




2. yarn global add create-react-app




3. create-react-app

This was my error:

3695 verbose argv "C:\Program Files\nodejs\node.exe" "C:\Users\****\AppData\Roaming\npm\node_modules\npm\bin\npm-cli.js" "install" "--save" "--save-exact" "--loglevel" "error" "react" "react-dom" "react-scripts"

This solved the issue:
