First of all, You need to use node js 10 or 12. Node js 14 isn`t compatible. Node 12 is but some libs aren’t, node 10 (in my opinion) is the best choice.
for handle node’s version on windows:

Like always, windows isn’t the best OS for programing, git doesn’t work well, but works. consider using a WSL (Windows Subsystem for Linux) like WSL | Ubuntu.
Edit: WSL 2: Getting started - YouTube
Hope, I’ve helped.
