Treehouse Guest TeacherI think this issue is is that you're using a newer version of Rails. It looks like you're using 4.0.0 Release Candidate 2. Use the same version as Jason Seifer in the videos and you should be fine.
Jed Bradshaw
6,053 PointsOk, I think I managed to get everything running (or at least I cut down on the error logs!). I am now running rails 3.2.13 and am trying to migrate. I get this error code now:
c:\Sites\treebook>rake db:migrate
rake aborted!
cannot load such file -- active_model
c:/Sites/treebook/config/application.rb:3:in require'
c:/Sites/treebook/config/application.rb:3:in<top (required)>'
c:/Sites/treebook/Rakefile:4:in `<top (required)>'
(See full trace by running task with --trace)
Also, when I try to start a server, the command console just spits out the 'Usage' directory. Andrew Chalkley
Edit: Solved. Answer here: https://teamtreehouse.com/forum/error-code-trying-to-migrate

Treehouse Guest TeacherWell done Jed!

6,053 PointsOk I think you are right, but now I am running into huge issues with trying to downgrade. I have uninstalled 4.0 and installed 3.2.13 multiple times (whilst also installing and using Bundler), in multiple directories also. When I check what version I am using the command console says 4.0 but when I use 'gem uninstall rails' it only lists 3.2 versions. I have also re-installed via my original Rails Installer .exe and it automatically installed 4.0. I even changed my code in Sublime: all references to 4.0 are now 3.2.13.
I don't get how I'm supposed to get to 3.2. I can't start a server either. It keeps giving me this error code: c:\Sites\treebook>rails s C:/RailsInstaller/Ruby1.9.3/lib/ruby/gems/1.9.1/gems/actionpack-3.2.13/lib/actio n_dispatch.rb:34:in `require': cannot load such file -- active_model (LoadError)

Mainly, I just want to get to 3.2.13. If I use Rails Installer it automatically installs 4.0. I'm not opposed to starting over. Thank you! Andrew Chalkley

Treehouse Guest TeacherHave you specified the version of rails in your Gemfile like this?
gem 'rails', '3.2.13'It looks like you possibly have a space between the 1 and 3 so you could have something like this:
gem 'rails', '3.2.1 3'Uninstall all versions of rails. Then
bundle installwith the correct Gemfile configuration.
