We had the same problem. This fixed it for us

project-root$ mysql.server stop
project-root$ gem uninstall mysql2
project-root$ bundle install
project-root$ mysql.server start

Answer 2

That's an issue with the latest mysql version that is installed via homebrew.

5.6.x creates the problem. downgrading to 5.5.x solved the issue for me.

You can install old formula versions pretty easily with homebrew:

brew versions mysql will give you the sha you have to checkout in /usr/local to be able to install an old version

   cd /usr/local
   git checkout 336c976
   brew info mysql

This will show you 5.5.29 as the mysql version. You can then uninstall mysql based on these instructions and reinstall simply by running

   brew install mysql

and running through the normal installation process with homebrew:

  unset TMPDIR
  mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Hope that helps.

You can checkout master in /usr/local after installing the old version of mysql after that again. The brew versions command even gives you the command to just checkout the formula for mysql but I don't think that has any advantages over just checking out the whole repository for the sha and then going back to master after installing the old mysql version.
