Not sure if this is the "right" thing to do, but I found this temporary hack somewhere on the internet. I had to change the path to where my grep was (the example online said to put it in /usr/bin/grep which didn't work for me.
alias grep="/bin/grep $GREP_OPTIONS"
unset GREP_OPTIONS
Apparently GREP_OPTIONS is being deprecated and throwing like 3 errors when running any command inside of a git reposity.
