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. 🙂 ---

Change that line and you should be good. Fred ---

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 On Feb 25, 1:26 pm, Frederick C.

The easiest way is probably just to install the rails gems again. Fred ---

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”? ---

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

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 ☹ On 25/02/2008, Mark B.
