Rails and DrX

[Ryan Taylor]

Hey, I really am stoked to have found DrX today. It looks awesome and like it will save me lots of time. That being said, it seems to fundamentally fail when trying to play with Rails. I don't want to model Rails, but my libraries I'm trying to map play next to Rails, and it seemed like there would be a larger user base for your gem if these played together.

Here is what I see:

If I try to load rails console and then require 'drx' =>

Loading development environment (Rails 3.1.3)  
ruby-1.9.3-p0 :001 > require 'drx'

from script/rails:6:in `<main>'

If I try to load my environment in an irb session I get the same error.

If I load drx first, I get the following, after a successful load =>

A bit late, but there are some good instructions here:

Basically, you need Tk support compile into ruby. I know some 1.9.2's have it, not sure about 1.9.3 you are using though. I think it's just that, no Tk support. You can compile ruby with it, although I'm not sure exactly how. That article I linked above has some comments at the bottom that detail the ways to install it via RVM.
