Heroku and Ruby Sets

So I'm building a Rails app and I was making use of the Set class that Ruby provides (docs here: http://www.ruby-doc.org/stdlib-1.9.3/libdoc/set/rdoc/Set.html).

In my code I have:

require 'Set'

and everything runs well locally.

However, Heroku seems to stumble, giving the error:

LoadError (cannot load such file -- Set)

I have tried googling but the broadness of the word "Set" seems to contaminate my results. Is there any way to setup Heroku to allow me to use the Set datatype?



You should simply do:

require 'set'

Libs shouldn't be capitalized.
