I've come up with an unusual problem right after installing Ruby+RoR. When I start server or console, I get these two errors:
C:/Ruby/lib/ruby/gems/1.8/gems/rails-2.3.4/lib/initializer.rb:602:in `send': undefined method `cache_template_extensions=' for ActionView::Base:Class (NoMethodError) C:/Ruby/lib/ruby/gems/1.8/gems/activesupport-2.3.4/lib/active_support/dependencies.rb:443:in `load_missing_constant':NameError: uninitialized constant ApplicationController
I see that "cache_template_extensions" defined to 'false' in environments/development.rb, so I added to environment.rb ENV['RAILS_ENV'] ||= 'development' just to make sure. (Even though initializer.rb sets it to 'development' by default anyway).
This is latest Ruby 1.8.6 and RoR 2.3.4 on a Windows Vista 64-bit desktop. I copied a small project that I was developing on another WinXP machine here and tried to start WEBrick with ruby script/server.
The project was originally done under InstantRails, which is based on RoR 2.0.2. So I updated to: RAILS_GEM_VERSION = '2.3.4' unless defined? RAILS_GEM_VERSION
None of this helps. When I start the console, I get those two messages, but the console starts. When I try to start a server (WEBrick), I get this full stack and it stops.
