I’m trying to get rails 2.3 to work on ubuntu 8.10. As now in synaptic  
manager, I saw rails 2.1.0 is installed, but when I do sudo gem install  
rails, i saw rails 2.3 got installed.

When I did a test by generating a blank rails project such as “rails -D  
mysql testproject\_01”, and then ran ./scripts/server to start rails  
server, I saw under information section listed my rails as 2.1.0.

How to stop rails 2.1.0 (Ubuntu default) as a default, and allow 2.3  
rails to be the default? Should I remove rails from synaptic manager?  
What files that I need to edit to have rails 2.3 becomes the default  
version on my system?

Thanks…

Oh guys, I found the solution on my own :). If anyone has similar  
situation, just uninstall your old rubygems from synaptic manager. Just  
make sure you remove all versions of rubygems from synaptic.

Go to [rubyonrails.org](http://rubyonrails.org) and download the source for rubygems. Extract the  
package, and then do ruby setup.rb. Then you have to do gem1.8 install  
rails --include-dependencies. Do rails -v to check to see what rails  
version you got! 🙂 My is now 2.3.2.
