Question

UPDATE:

I found the simple answer and it’s completely my own fault: I stored the above code in a file called “eventmachine.rb”. Thus when I required ‘eventmachine’ it just imported the same file, which does not contain a definition for EventMachine.

So this is not really a post about EventMachine.

ORIGINAL POST:

Excuse me, but what’s going on?

require 'rubygems'
require 'eventmachine'

EventMachine

gives

uninitialized constant EventMachine

in both TextMate and on the console when I run “ruby myfile.rb”.

But if I type the same thing into IRB, I get

=> EventMachine

.

…

I got so frustrated that I followed the rash instructions on http://blog.carlmercier.com/2007/12/14/how-to-fix-that-rubygems-mess-on-leopard/ — wiping out my Ruby and Rubygems environments and reinstalling them from MacPorts. IRB still works and TextMate/commandline still fails in the same way. I even reduced my TextMate PATH to the one place where Ruby, Gem, and IRB are installed now: /opt/local/bin — which is what Which reports.

Finally, when I

puts Gem.path

on either IRB, TextMate, or the console, I get the same path.
