Since OSX el Capitan there is a new security function that prevents you from modifying system files called Rootless. So you have 2 options:
If you install gems on
/usr/local/binthere will be no problem because rootless doesn't affect this path.sudo gem install -n /usr/local/bin GEM_NAME_HERE
You are experiencing this issue because of a new security feature called System Integrity Protection
