rails not installing

Question

When I run the gem command to install rails on my macbook pro early 2011, it seems to install it, but then when I run any rails command the terminal gives me an error saying that rails is not currently installed on the system any help please?

The command I'm using to install rails is:

sudo gem install rails

Then the terminal outputs:

Successfully installed rails-3.2.8
1 gem installed
Installing ri documentation for rails-3.2.8...
Installing RDoc documentation for rails-3.2.8...

Then I execute a command like:

rails --version

And the following error shows up on the terminal:

Rails is not currently installed on this system. To get the latest version, simply type:

$ sudo gem install rails
