Essayant de passer de Rails 2.3.5 à 3.0.1 sur Heroku, mais Heroku pense toujours que j'utilise 2.3.5

Question

J'utilisais auparavant Ruby 1.8.7 & Rails 2.3.5 sur Heroku.

J'ai mis à niveau mon environnement de développement vers Ruby 1.9.2 et Rails 3.0.1 en utilisant les instructions this railscast. RVM est utilisé, donc les versions système de Ruby et Rails sont toujours 1.8.7 & Rails 2.3.5 respectivement, mais j'ai un environnement RVM avec 1.9.2 et 3.0.1, que j'utilise maintenant. J'essaie maintenant de faire fonctionner les nouvelles versions sur Heroku. Je suis passé de Heroku stack à bamboo-mri-1.9.2 et j'ai fait git push heroku master. Cela a semblé fonctionner:

-----> Heroku receiving push 
-----> Migrating from bamboo-ree-1.8.7 to bamboo-mri-1.9.2 

-----> Rails app detected 
-----> Detected Rails is not set to serve static_assets 
     Installing rails3_serve_static_assets... done 
-----> Gemfile detected, running Bundler version 1.0.0 
     Unresolved dependencies detected; Installing... 
     Fetching source index for http://rubygems.org/ 

     (gems installing here) 

     Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed. 

     Your bundle was installed to `.bundle/gems` 
     Compiled slug size is 5.9MB 
-----> Launching.... done 
     http://www.(website url).com deployed to Heroku 

-----> Migration complete, your app is now running on bamboo-mri-1.9.2 

Mais j'essayé de faire heroku rake db:migrate et a obtenu cette erreur:

Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

Pour une raison quelconque, il pense toujours qu'il fonctionne sur Rails 2.3.5. Qu'est-ce qui cause ce problème? Merci d'avoir lu.

Je pense que vous devez changer quelle pile votre machine locale pointe. Qu'est-ce que
