It is possible that all dependencies are not installed. If you have not used rvm to install ruby, you should try using it to install your ruby version.
rvm install 1.9.3
or
rvm reinstall 1.9.3
refer https://rvm.io/rvm/install for step by step instructions.

I'm just starting out with Rails and am following the Ruby on Rails essential training course and get problems trying to start WEBrick. Assuming it has something to do with my installation of mysql but not sure.
I made sure that I am in the correct directory (:C\sites\simple_cms)
I ran 'bundle install' before running 'rails s'
I followed these guides to get the gem installed (second to last entry): https://github.com/brianmario/mysql2/issues/372
I have ruby 2.2.1p85, rails 4.2.1 and this rubygem: mysql2-0.3.18-x64-mingw32 installed
Would appreciate some help from y'all :)

I have solved this, eventually!
I re-installed Ruby and Rails under RVM. I'm using Ruby version 1.9.2-p136.
After re-installing under rvm, this error was still present.
In the end the magic command that solved it was:
I want to continue programming a rail app but the following error occurs when I try to start the server rails s.
My rail installation seems to work fine when I have a brand new directory (it uses sqlite3 there). I also probably have everything installed, xcode, homebrew, RVM...
Operating system: OS X, 1.8.2
Any ideas to solve this error?

The location is different on osx, look for /private/var/mysql/mysql.sock
Your options are to change the socket value in database.yml or create a symbolic link at /tmp/myslq.sock
I prefer the later since it's a common issue.
