I've this same issue, do you have a solution?

EDIT (solution):

$ sudo chown -R $USER:admin /usr/local
$ brew install git
# optionally (if trouble with `brew link git`)
$ brew link --overwrite git

It already resolved my problem.Thank you.

This helped me resolve my problem too. Thank you!

$ brew link --overwrite git
worked for me.
