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 been working on Ruby on Rails since 2 months go and now I want to change the database system so I installed the gem mysql2 by this command:
gem install mysql2 --platform=ruby -- '--with-mysql-lib="C:\mysql-connector\lib" --with-mysql-include="C:\mysql-connector\include" --with-mysql-dir="C:\mysql-connector"'
And It works!
but the problem is when I want to run rails server again I got this error

Most likely you need to regenerate libmysql.lib as described here:

I installed mysql by downloading the mysql-controller-c ,but it still reports me an error, and l copied libmysql.dll to ruby/bin ,also I copied it to system32,and it still have the problem,can someone give me a suggestion to solve it.
This gem does not have prebuilt native extension for Ruby-2.0 (see C:\Ruby\lib\ruby\gems\2.0.0\gems\mysql-2.9.1-x86-mingw32\lib\mysql). You will have to build it yourself or downgrade to ruby-1.9.

I have solved this, eventually!
