Quick Tip: Sprinkle, passenger-stack, and Rails 3
If you’ve tried to get passenger-stack and Sprinkle 0.3.1 running recently, you might have run into the not-so-helpful error: uninitialized constant ActiveSupport::Dependencies (NameError).
It appears that if you have one of the Rails 3 beta gems installed, then Sprinkle gets confused when trying to use ActiveSupport’s Dependencies module. This error can be fixed by modifying lib/sprinkle.rb in the gem directory. Add the following line right after require ‘activesupport’ (line 2):
require 'active_support/dependencies'
Hopefully the author of Sprinkle will get this bug fixed up soon. An issue on Github has been created.
Update: Github user ahaller has submitted a patch. It sounds like it’s OK to just add the require line even if you are on Rails 2.
Thanks for this piece of useful information. Just an update on this, if sprinkle.rb is absent in your ruby setup, add this line
require ‘active_support/dependencies’
to lib\ruby\gems\1.9.1\gems\activesupport-3.0.3\lib\active_support.rb
