Ruby On Rails: Error on rake db:migrate

I am pretty new to rails environment. I am learning it from Pluralsight's Ruby on rails for .Net Development: I am trying to run rake db:migrate and getting the following error:

D:\Rails\MyBlog>rake db:migrate
rake aborted!
126: The specified module could not be found.   - C:/RailsInstaller/Ruby1.9.3/li
D:/Rails/MyBlog/config/application.rb:7:in `<top (required)>'
D:/Rails/MyBlog/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)

The only difference between the course I am learning and my implementation is that I am using MySql and the course uses SQL Server 2008.

What could be the reason behind the error? Any Help?



bundle install

That, you've probably done.
