You are running `create-react-app` 4.0.3, which is behind the latest release (5.0.0). We no longer support global installation of Create React App
Solution 1:
try clearing npx-cache if you recently ran this on older version.
npx clear-npx-cache
npx install -g create-react-app react-app
Solution 2:
Also what one can do is enter the console as administrator, located in the user's folder, and put this command (in my case I used the NPM one)
npm uninstall -g create-react-app
we uninstall it and then I reinstall it
npm install -g create-react-app
and voila, it worked for me
Solution 3:
i used npx create-react-app@latest my-app . this worked for me
