I have a strange issue. My rails environment is fully functional with  
enterprise ruby, rails 2.3.5, running on passenger in production. In  
my .irbrc I am trying to include wirble gem for auto completion and  
coloring so I add the following lines and install wirble. As soon as I  
do that, it messes up my rails install and throws an error saying  
“rails gem is not installed”, though it’s. If I uninstall wirble and  
leave these lines in .irbrc the problem goes away. I am guesing it has  
something to do with the ‘require rubygems’, but this is not a problem  
in my development environment. I have the same .irbrc, the only  
difference is my dev environment runs regular ruby 1.8.7 not  
enterprise ruby

require ‘irb/completion’  
IRB.conf[:PROMPT\_MODE] = :SIMPLE  
require ‘rubygems’  
#require ‘RMagick’  
require ‘wirble’

if ENV[‘RAILS\_ENV’]  
require ‘rubygems’  
require ‘hirb’  
require ‘active\_record’  
Hirb.enable  
ActiveRecord::Base.logger = Logger.new(STDOUT)  
end

Any ideas?

Thanks

Here is the exact error.

Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`,  
update your RAILS\_GEM\_VERSION setting in config/environment.rb for the  
Rails version you do have installed, or comment out RAILS\_GEM\_VERSION  
to use the latest version installed

Rails is installed!

xxx@server:/var/www/myapp/current$ rails --version  
Rails 2.3.5
