Hi, I have a problem upgrading to rails 2.0, my current installation of rails is version 1.2.4 installed through the official Ubuntu repository (apt-get install rails), I installed rails through: gem install rails --include-dependencies and everything looked fine but the problem is that the old version of rails still running and I don’t know where to find the new version and how would I get a rails 2.0 application when I run :“rails MyApp”.
Your help is highly appreciated.
There's a line in environment.rb which locks the app to a specific version of rails. Change that line and you should be good.

environment.rb is generated when you create a new rails app :"rails MyApp", right? The problem is that I'm unable to create new rails app, I got:"Command 'rails' is available in '/usr/bin/rails' bash: rails: command not found " because I did a stupid thing I removed the old version thinking that it prevents rails 2.0 from working and now I've got nothing that works. Rails 2.0 is installed but I don't know where, I just need to fire it up when i run rails MyApp.
Thanks

Ah yes, the actual rails binary is just a thing that says 'load up the
rails gems and run x'. The easiest way is probably just to install the
rails gems again.

Hi, "gem install rails --include-dependencies Need to update 30 gems from http://gems.rubyforge.org … complete Successfully installed rails-2.0.2 "
But still:
"rails myapp Command ‘rails’ is available in ‘/usr/bin/rails’ bash: rails: command not found "
??

Does the command: type rails confirm that you are finding rails in /usr/bin/rails?
If it says something else, then try running: hash rails
Can you run:
rails --version ? If not, how about: /usr/bin/rails --version ?
If not, what's the first line of /usr/bin/rails? rails should be a script and the first line should refer to your ruby executable. Something like one of these:
#!/usr/bin/ruby
#!/usr/bin/env ruby
If the first, can you run the command directly by the path specified (so /usr/bin/ruby in my example)? If the second, can you run ruby as "ruby"?
Hi, type rails and hash rails gives a message that rails is not found. The rails version check tells me that “No such file or directory” ! So I don’t have a rails file at all in /usr/bin although gems insists that Rails 2.0 is installed and i don’t know where it is !!!
I don’t have problem with ruby, I can run ruby as ruby

It sounds like you need to update gems. Try:
gem update --system
Then install rails again.
