Thanks guys. Here’s another question: I used this command: rake rails:freeze:edge TAG=rel\_2-0-1 But now when I try to start the server I get this error: …vendor/rails/railties/lib/initializer.rb:159:in `require_frameworks': no such file to load -- active_resource (RuntimeError) from /.../vendor/rails/railties/lib/initializer.rb:88:in`process’ from /…/vendor/rails/railties/lib/initializer.rb:49:in `send' from /.../vendor/rails/railties/lib/initializer.rb:49:in`run’ from /…/config/environment.rb:14 from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb: 27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 27:in`require’ from /…/vendor/rails/activesupport/lib/active\_support/ dependencies.rb:496:in `require' from /.../vendor/rails/activesupport/lib/active_support/ dependencies.rb:342:in`new\_constants\_in’ … 21 levels… from /…/vendor/rails/activesupport/lib/active\_support/ dependencies.rb:496:in `require' from /.../vendor/rails/railties/lib/commands/server.rb:39 from script/server:3:in`require’ from script/server:3 Could I ask for advice on what the problem is?

The first time you run this, you’re running the rails 1.2.x version of the rake task, that doesn’t know about activeresource (and so doesn’t download it). The second time you’re running the rails 2.0.1 version of the rake task, which does know about activeresource. Fred ---

Run it again and this time, when trying to start the server I get a different error: /…/vendor/rails/actionmailer/lib/action\_mailer/base.rb:354:in `method_missing': undefined method `server\_settings=’ for ActionMailer::Base:Class (NoMethodError) from /…/config/environment.rb:68 from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/ custom\_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in `require’ from /…/vendor/rails/activesupport/lib/active\_support/ dependencies.rb:496:in `require' from /.../vendor/rails/activesupport/lib/active_support/ dependencies.rb:342:in `new\_constants\_in’ from /…/vendor/rails/activesupport/lib/active\_support/ dependencies.rb:496:in `require' from /usr/local/lib/ruby/gems/1.8/gems/mongrel-1.0.1/lib/ mongrel/rails.rb:155:in `rails’ from /usr/local/lib/ruby/gems/1.8/gems/mongrel-1.0.1/bin/ mongrel\_rails:112:in `cloaker_' ... 18 levels... from /.../vendor/rails/activesupport/lib/active_support/ dependencies.rb:496:in `require’ from /…/vendor/rails/railties/lib/commands/server.rb:39 from script/server:3:in `require’ from script/server:3 My config/environment.rb has the following: 65 ActionMailer::Base.delivery\_method = :smtp 66 67 c = YAML::load(File.open(“#{RAILS\_ROOT}/config/config.yml”)) 68 ActionMailer::Base.server\_settings = { 69 :address =\> c[RAILS\_ENV][‘email’][‘server’], 70 :port =\> c[RAILS\_ENV][‘email’][‘port’], 71 :domain =\> c[RAILS\_ENV][‘email’][‘domain’], 72 :authentication =\> c[RAILS\_ENV][‘email’][‘authentication’], 73 :user\_name =\> c[RAILS\_ENV][‘email’][‘username’], 74 :password =\> c[RAILS\_ENV][‘email’][‘password’] 75 } 76 CONTACT\_RECIPIENT = c[RAILS\_ENV][‘email’][‘contact\_recipient’] Should I run it again? or is this a different problem?
