Pourquoi suis-je recevoir cette erreur? Y a-t-il une config qui me manque?

De plus, y a-t-il un bon tutoriel emacs ruby ​​on rails pour un novice?

Merci pour l'aide

Answer 1

Il semble que vous avez 2 versions de Rails installés: 2.3.8 (comme dans des rails -v) et 2.3.3 (comme dans le journal des erreurs). Faire appliquer la plus récente dans votre application:

# config/environment.rb 
RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION 

Vous pouvez utilisateur rvm pour basculer entre eux. La chose la plus simple à faire, cependant, est de désinstaller les paquets Ubuntu-rails et d'installer le rail gem.

La méthode cookie_verifier_secret= est obsolète, vous pouvez donc les commenter en toute sécurité.
