Hi,    I am a new guy in Ruby on rails.I have installed ruby1.9.2p180, rails 3.2.1, gem 1.8.15,mysql,apache 2.0 and JetBrains RubyMine 3.1.1 .    Whenever, I am creating the application through he command prompt by "rails new Blog" then "Blog" application is creating successfully and start the server under "Blog" by "rails server". But whenever, I am creating the project through the RubyMine IDE, lets say "Apt" and trying to switch on the server, getting the following issue:

C:/ruby/lib/ruby/gems/1.9.1/gems/mysql2-0.3.11-x86-mingw32/lib/mysql2/mysql2.rb: 2:in `require': Incorrect MySQL client library version!

It seems you have changed your MySQL version. You can try reinstalling mysql2 gem using:

gem uninstall mysql2

gem install mysql2

Hi Prince,   I uninstall mysql2 and install again. After creating new project through RubyMine IDE, one message is showing like "Some of the required gems are not attached:coffee-rails(~>3.2.1),jquery-rails,mysql2,sass-rails(~>3.2.3),uglifier(>=1.0.3)" Also "Attach gems" link is there. shall I click on that? By the way, after re-installing mysql2, I am getting the same issue again.
