Let's say you're running this command:
npx gulp
npx will search for gulp within node_modules/.bin, and if it doesn't find it there, it will use a central cache. If it is missing, npx will install it.
How do I clear the central cache to force npx to reinstall gulp in this case?
On macOS (and likely Linux) it's ~/.npm/_npx, you can drop it with:
rm -rf ~/.npm/_npx
On Windows it should be %LocalAppData%/npm-cache/_npx
Either way, you can find npm’s cache by running npm config get cache and then finding an npx folder in there.
I needed to do this, due to an error in create-react-app saying 'We no longer support global installation of Create React App.' despite there being no global install. It was stuck in the npx cache, and I removed it like this
npx clear-npx-cache
