How do I make git work again? And why is Xcode not updating?-CodePudding

Recently tried to use git on a Mac to push changes to a repository, and it's no longer working. It eventually led me to find other issues as well.

  Referenced from: /usr/local/bin/git

zsh: abort      git --version

Then I tried brew install git :

  Referenced from: /usr/local/bin/git
  Reason: image not found
