I have got the same error using npx create-react-app my-app

I'm not aware of what was causing the problem but I found this and solved. Hope it can help.
In short:

sudo npm cache clean -f
npm install -g n
sudo n stable
npx create-react-app my-app

Node helper n doesn't work on windows.
Force clearing the cache helped solve my problem.
Thanks @JacopoBonta
