Got the following error on Mac

Hi

My first attempt to learn React and came across the following error when I did this on Mac. Appreciate the help in sorting the issue

(base) Kalpanas-MacBook-Air:/ kalpana$ create-react-app my-app
/usr/local/lib/node_modules/create-react-app/node_modules/fs-extra/lib/mkdirs/mkdirs-sync.js:45
throw err0
^
