Unable to get RAILS 3 recognize the Ruby 1.9.2 on Ubuntu 10.04

I have fresh install of Ubuntu 10.04.

I have installed Ruby 1.9.2 and RAIL 3 as per this blog
http://torqueo.net/installing-ruby-192-and-rails-3-stable-on-ubuntu/.

When I run "ruby -v', I see this;

srikanth@ubuntu:~$ ruby -v
ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]
srikanth@ubuntu:~$
srikanth@ubuntu:~$ which ruby
/usr/local/bin/ruby
srikanth@ubuntu:~$

However, RAILS complaints that I am using Ruby 1.9.1.
srikanth@ubuntu:~$ rails -v

    Rails 3 doesn't officially support Ruby 1.9.1 since recent stable
    releases have segfaulted the test suite. Please upgrade to Ruby
1.9.2
    before Rails 3 is released!

    You're running
      ruby 1.9.1p378 (2010-01-10 revision 26273) [x86_64-linux]

Rails 3.0.0
srikanth@ubuntu:~$

Even when I try to specify explicity ruby path, "rails' still
complains

srikanth@ubuntu:~$ rails -v --ruby=/usr/local/bin/ruby

I tried creating new app, and I get errors related to "Bundler" when
launching the app

srikanth@ubuntu:~/rails-workspace/myapp$ rails server
/home/srikanth/rails-workspace/myapp/config/boot.rb:9:in `rescue in
<top (required)>': uninitialized constant Bundler (NameError)
  from /home/srikanth/rails-workspace/myapp/config/boot.rb:5:in `<top
(required)>'
  from script/rails:5:in `require'
  from script/rails:5:in `<main>'
srikanth@ubuntu:~/rails-workspace/myapp$

I am not sure how to get RAILS recongnize the fact that I have Ruby
1.9.2 installed.

Any help will be great.

Thanks,
Srikanth

What does the shebang inside the rails executable look like ?

Here it is:

#!/usr/bin/ruby1.9.1

You should install Rails for this copy of Ruby i.e. gem install rails. Check your Ruby version first with ruby -v.

Looks like version 1.9.1 was pre-installed on Ubuntu 10.04 as there was a file /usr/bin/ruby1.9.1 that RAILs seems to have been picking up.

I unintalled Ruby from “System -> Adminitstration -> Synaptic Package Manager”.

I deleted all the contents of “/usr/local/ruby”.

And re-installed Ruby 1.9.2 and all the RAILS gems as per the blog http://torqueo.net/installing-ruby-192-and-rails-3-stable-on-ubuntu/.

Now, things are working just fine.

You might install rvm as well. I've fund it to be very helpful being
able to have multiple - isolated - ruby and rails versions. One of the
best features is to have a per project gem setup.

I had problems with ruby on Kubuntu without rvm, now it is smooth
sailing
