"no such file to download - net / ssh" from rails Controller on Ubuntu

Question

I have a very simple controller:

require 'net/ssh'

class MyController < ApplicationController
    def foo
        render :text => 'bar'
    end
end

But when I request http: // server: 3000 / my / foo , I get:

MissingSourceFile in MyController#foo 
no such file to load -- net/ssh

Stone set

> gem list net-ssh

*** LOCAL GEMS ***
net-ssh (2.0.11)

Also, I tried to use "net / ssh" in IRB and it works.

MyController works fine on Windows, but not on Ubuntu.

What could be wrong?

Answer 6

I think the original problem was that instead of a regular user, I used a regular user:

$ gem install net-ssh
  WARNING:  Installing to ~/.gem since /usr/lib/ruby/gems/1.8 and
            /usr/bin aren't both writable.
  WARNING:  You don't have /home/alex/.gem/ruby/1.8/bin in your PATH,
            gem executables will not run.

So, I think the rails could not find this stone.
