问题:
First time running brew since 10.9 upgrade.
From the output below, should I just remove Library/Formula/ant.rb and Library/Formula/apple-gcc42.rb? Also, unclear why git pull is failing. Thanks for any help

This fixed it for me
cd `brew --prefix` git fetch origin git reset --hard origin/master
brew update worked fine after that

Solution
You might still find..
brew update not working after git pull origin master
Here what you need to do.
cd /usr/local git pull origin master brew install git
Now you might already have git on your System, but what this will do it that now.
Your broken brew update will automatically be updated before at first run..
Here is the link to the origin issue in HomeBrew. brew stuck

I simply removed the .git directory inside of the /usr/local directory, then ran the command brew update.
回答4:
I did this to solve the problem
cd /usr/local git pull origin master
回答5:
My brew update was hanging and doing nothing. I am on OSX 10.12.5 and none of the above worked for me and I have no .git in usr/local, only in usr/local/Homebrew.
I ran brew update --debug --verbose and brew update and that fixed the issue, see this issue: https://github.com/Homebrew/brew/issues/895
