Brew update does not work after mac 10.9

Question

The first launch of brew since the 10.9 update.

From the result below, just remove Library / Formula / ant.rb and Library / Formula / apple-gcc42.rb? In addition, it is not clear why git pull does not work. Thanks for any help

Answer 1

It fixed it for me

 cd 'brew --prefix'/Homebrew git fetch origin git reset --hard origin/master 

Brew update worked fine after that

Answer 2

Decision

You can still find ..

brew update doesn't work after git pull origin master

Here is what you need to do.

cd /usr/local git pull origin master brew install git

You may now have git on your system, but what will it do now.

Your broken brew update will be automatically updated before the first launch.

Here is a link to the original problem in HomeBrew. brew stuck

Answer 3

I simply deleted the .git directory inside the /usr/local directory, then brew update .

Answer 4

I did this to solve the problem

 cd /usr/local git pull origin master 

Answer 5

My brew update hung and did nothing. I am on OSX 10.12.5, and none of the above worked for me, and I do not have .git in usr/local , only in usr/local/Homebrew .

I ran brew update --debug --verbose and brew update and fixed the problem by looking at this problem: https://github.com/Homebrew/brew/issues/895

Answer 6

What worked for me was to update the brew like this :

 /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
