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

I searched in the source and it looks everything ok,I have no idea why I got this error.

I would appreciate your help guys,
Thanks!
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'm trying to install Redmine on my fedora machine and I have been following the official wiki to install it, I have gotten up to step 5 when I am asked to run the
*rake generate_secret_token*
command, however when I do I get this error

I am running the command as root. This is the guide I used http://www.redmine.org/projects/redmine/wiki/RedmineInstall
Do you have installed the necessary native libraries for mysql2 adaptor ?

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:
