'serveur rails de "commande" pas de travail dans le terminal

Je suis assez nouveau à rails, et en essayant de configuration extrêmement simple site de test.

J'ai créé la nouvelle application rails répertoire à l'aide de la rails new de commande, mais ensuite, impossible de configurer le serveur pour afficher la page dans un navigateur.

(Ci-dessous le message que je reçois lorsque la tentative rails server)

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.
Example:
rails new ~/Code/Ruby/weblog
This generates a skeletal Rails installation in ~/Code/Ruby/weblog.
See the README in the newly created application to get going.
