i am using node version 16 – Thermocline

is git installed on your system (try git --v)? can you try yarn create react-app my-app? – Antimonous

I am seeing the same problem while also trying node 16. – Pinzler

@PriyeshRanjan, did you figure out a solution by chance? – Pinzler

Answer 1

This error simply shows difference between version of global packages..update windows, npm, node remove cached memory in node. sometime reconnect to internet will help in this error..
