Uninitialized constant File::NOCTTY error when I require 'fakefs' - ruby

Question

I am trying to use FakeFS but keep getting an uninitialized constant error when I require 'fakefs':
C:/Ruby192/lib/ruby/gems/1.9.1/gems/fakefs-0.3.1/lib/fakefs/file.rb:26:in `<class:File>': uninitialized constant File::NOCTTY (NameError)
I was originally working in RubyMine, but to isolate the problem I wrote a simple hello world script and ran it from the command line, and still get the same error. Here is that script:
require 'rubygems'
gem 'fakefs'
require 'fakefs'
puts "Hello Cleveland!"
And here is the error and accompanying stacktrace:
>ruby foo.rb
C:/Ruby192/lib/ruby/gems/1.9.1/gems/fakefs-0.3.1/lib/fakefs/file.rb:26:in `<class:File>': uninitialized constant File::NOCTTY (NameError)

I installed the fakefs gem via RubyMine. I'm working on Windows with Ruby 1.9. Any ideas?

Answer 1

It's because Windows doesn't have NOCTTY and SYNC flags. You can add this method to the base.rb file:
def RealFile.const_missing const
const_set const, 42
end
Really, I don't know it cause any problems or not in the future but you'll be able to run your script at least. And I think you should write about this at github
There is a fork with some windows fixes (this guy commented all flags at all): https://github.com/vertiginous/fakefs
