rails server does not start any server

Question

I am a complete Ruby on Rails newbie following the railstutorial.org I just installed rails 3.2.13, created a project with rails new.

However I could not started the server using the command:

rails server

It returns the railscommand help message below (instead of WEBrick info) which does not mention the servercommand at all. So how can I start the server? Thanks

Description:
  The 'rails new' command creates a new Rails application with a default
  directory structure and configuration at the path you specify.

  You can specify extra command-line arguments to be used every time
  'rails new' runs in the .railsrc configuration file in your home directory.

Note that the arguments specified in the .railsrc file don't affect the
defaults values shown above in this help message.
