I have the HTTParty gem on my system and I can use it from within rails.

Now I want to use it standalone.

I am trying:

class Stuff
  include HTTParty
  def self.y
    HTTParty.get('http://www.google.com')
  end 
end
Stuff.y

but I get 

$ ruby test_httparty.rb 
test_httparty.rb:2:in `<class:Stuff>': uninitialized constant Stuff::HTTParty (NameError)
        from test_httparty.rb:1:in `<main>'

You have to require 'httparty':

require 'httparty'

class Stuff
  include HTTParty
  # ...
end

Its all because of the include which exists with in the class

If you include a class with a module, that means you're "bringing in" the module's methods as instance methods.

If you need more clarity on include and require

I request you to refer to this wonderful SO Posting

What is the difference between include and require in Ruby?

Here is an example which I have taken from the same posting 

 module A
   def say
     puts "this is module A"
   end
 end

 class B
   include A
 end

 class C
   extend A
 end
B.say => undefined method 'say' for B:Class

B.new.say => this is module A

C.say => this is module A

C.new.say => undefined method 'say' for C:Class
