Ruby error while trying to run wxRuby first application

I copied the sample code from wxRuby documentation and trying to run on
my IDE (Rubymibe), but it is giving errors. The code I am trying is
below:

=========== [CODE] =============
require “wx”
include Wx

class MainWindow < App
def on_init
Frame.new(nil, 0).show()
end
end

MinimalApp.new(MainWindow)

The errors are below:

You’ve installed the gem for Ruby 1.8. To resolve the problem,
uninstall the “wxruby” gem and instead install “wxruby-ruby19”.

Thanks it worked.
