Homebrew always prompted fatal: Invalid gitfile format: .git

Question

I'm using oh-my-zsh

➜  ~ brew -h  
fatal: Invalid gitfile format: .git
fatal: Invalid gitfile format: .git

➜  ~ brew update
fatal: Invalid gitfile format: .git
fatal: Invalid gitfile format: .git

How to fix this problem？

Answer 1

Do you have a .git file under ~, which happens to be empty?

In my case, I cannot do git command under, say my/path,. I found an empty file in my/path, I deleted that file and everything works now.
