Hi,

I'm trying to start the console (irb) in Ruby 1.9 with Rails 2.3.4. I have two versions installed of Ruby (1.9 & 1.8.6) and I run the Ruby 1.9 by calling: rake19, ruby19, gem19...etc

And they work fine in all situations except this! it seems that its trying to load Ruby 1.8 instead! Do you know how I can change that?

This is happening because script/console is calling irb (1.8). Assuming you have irb19 for ruby 1.9 you could do:

script/console --irb='irb19'

However there may still be problems with rails gems. If so, I'd recommend using rvm to manage your different rubys. When using rvm you will need to install gems separately for ruby 1.9 and 1.8.

Thanks...This Solved it :)
