Hello. I am getting this error… C:/dev/ccx\_aucxtion\_ccx/config/boot.rb:20:Warning: Gem::SourceIndex#search support for String patterns is deprecated c:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:149:in `activate’: can’t activate activesupport (= 1.4.4, runtime), already activated active support-2.2.2 (Gem::Exception) Is there a way to specify the Active Support version in environment.rb? I see there is a way to specify the Rails version… RAILS\_GEM\_VERSION = ‘1.2.6’ unless defined? RAILS\_GEM\_VERSION Please let me know. Thanks, John ---

I see there is a way to specify the Rails version… A particular version of rails is tied to a particular version of activesupport. The error message you’ve got means that something required a newer version of activesupport before rails loaded its version. Fred
