Install MySQL first, either by using binary or Homebrew.

Then:

gem install mysql2

Or:

gem install ruby-mysql

Just pick one and you are good to go.

Edit

In case you upgraded to MySQL version 5.6.12 on OS X, mysql2 will fail to compile. Solution is to downgrade MySQL as described here: https://stackoverflow.com/a/17252887/45254

Edit2

In case you don't want to have mysql installed (maybe you use docker to manage your services) but do want to use mysql2 gem, you can instead install mysql-connector-c (using homebrew).
