Help with net/ssh

Rails
1

hey guys,
I’m new to Ruby and Rails.
My setup is Locomotive on Mac OS X.

When I try to run the below code, I get the below error. What do you
guys think?

Code:
require ‘net/ssh’

session = Net::SSH.start( ‘clipper.eiu.edu’, ‘xop’, ‘xop1748’)

puts ‘successful’
session.close

Output:

~/Documents/Programs/Ruby/Depot$ ruby ssh_test.rb
ssh_test.rb:1:in `require’: no such file to load – net/ssh (LoadError)
from ssh_test.rb:1

Thanks,
Dev
