Reproducible Demo

The above error is due the white space contain in your username of PC. The command npx create-react-app doesn’t work in this situation and shows error. I have fixed the error and created my first react app. https://github.com/philson-philip/react-skills Check the above link for solving the problem and creating your first app with react. Commands are detailed in the README.md file.

I should say that I’m using npx on WSL and not having any issues. So it definitely seems to be an npx issue sadly 😕

To give yourself less headaches in future, you could rename your computer?
