Rails

Hello G.s ,

I have started upgrading my rails application , when i have started
upgrading i was only upgrading only the rails version from rails
2.3.11 to rails 3 and now i have to upgrade the ruby version as well
from ruby 1.8.7 to ruby 1.9.2 , So i have installed ruby 1.9.2 using
RVM and by setting the ruby 1.9.2 when i am trying to run my
application with ruby 1.9.2 and rails 3, it is not working and i am
also not able to run any rake command it is showing me

no such file to load – config/environment

So guys can you please tell me what is right approach to upgrade ruby
version for an application.

Thanks
Nishant

I have found the best way is to create a Rails 3 gemset using RVM, then
create
a .rvmrc file telling your project to use it. Make sure you run Bundle
to
install the gems into the isolated gemset.

Also keep in mind that many of the console level commands have changed,
and
the supporting libraries. You may need to run “rails new .” to update
the
base files, but BE AWARE this will want to overwrite your project files
(don’t
worry, it will ask you). I highly recommend using git (or similar) to
see the
differences made and update the code as required. This can be a painful
process - perhaps someone here has an easier way?
