Amrit, there may be something within your environment which may be
causing
this issue. You’ll have
to check how you have installed things. In general, 1.8.7 usually
refers
to the version of Ruby installed
on your system. At this time, the latest version of Rubygems is 1.8.5
as
far as I know.

Good luck,

-Conrad

If you’re using Rails 3.0.7, then you should have a Gemfile in the root
of your Rails project.

       Strange!!
    This project dont have Gemfile

If you’re using Rails 3.0.7, then you should have a Gemfile in the root
of your Rails project. Within the Gemfile, you would add an entry to
use Rails 3.0.7. For example,

gem ‘rails’, ‘3.0.7’

Next, you’ll run the bundle command at the root of your Rails project:

bundle install

Last but not least, I would highly recommend the following site:

Good luck,
