How to install react app without an error

Question

Hello guys i am trying to install react into my system but from 2 days i am facing the error for several times now. At first, i have used these commands to install react app and it was working fine for me

1. npm install -g creat-react-app
2. create-react-app reactapp

but form 2 days i was facing error while choosing these options to install, therefore I visited https://create-react-app.dev/docs/getting-started/ where it was clearly stated- If you've previously installed create-react-app globally via npm install -g create-react-app, we recommend you uninstall the package using npm uninstall -g create-react-app to ensure that npx always uses the latest version. Then i used the command npx create-react-app reactapp but i am facing this error. I have multiple time uninstalled nodejs and installed, also have used the command npm cache clean --forcetoo. But not working!!!!

e:\react-learn>npm uninstall -g create-react-app
removed 98 packages in 5.031s

e:\react-learn>npx create-react-app reactapp
npx: installed 98 in 39.888s

npm cache clean --force

or

Try using npx create-react-app client --use-npm. Sometimes some issues arise due to package managers .
