Answer №1

I encountered a similar issue and resolved it by clearing my npm cache with the command

npm cache clean --force 

You can verify if your npm cache has been successfully cleaned by using

npm cache verify

After that, attempt to run

npx create-react-app (Your App Name)

This should resolve the issue

Answer №2

Your issue could be due to your system searching for dependencies on an incorrect URL. Try the following solution:

npm config set proxy null
npm config set https-proxy null
npm config set registry http://registry.npmjs.org/
