Gem Rails Version Showing Wrong?

[Tiago Rossi]

Hello, and first of all, Im starting with ruby and Ive installed into my server, sorry for my newbie question here guys.

After install rails when I type rails -v it shows Rails 2.3.18 but after I type gem dependency rails it shows Gem rails-4.2.0 and other dependencies.

Please, what are the real version?

Thanks very much.

Like that:

#rails -v

Rails 2.3.18

# gem dependency rails

Gem rails-4.2.0

...show the dependencies
