I'm trying to upgrade my Rails 2.3.5 app to Rails 3, and when I try
and start the rails server with 'rails s' I get this:
dependencies.rb:239:in `require': no such file to load -- activerecord
Using Mac OS X Snow Leopard, and it seems the error traces back to the
config.ru file in the first line:
require ::File.expand_path('../config/environment', __FILE__)
I copied this config.ru file from a fresh Rails 3 app.
