I have installed rvm. After creation of a gemset for a new project, when i give the command rails server, it shows this error report_activate_error': Could not find RubyGem railties (>= 0) (Gem::LoadError)
from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:211:inactivate`

So i found a solution that i need to give the command gem install rails to install rails.
Is it necessary to install rails for every new project? I am confused. Please guide me the real thing. Thanks.

    Gemsets are separating environments, you need to install gems for every new gemset, if you will always use the same version of rails you can install gems in global gemset:

    rvm @global do gem install rails
