Installez mysql2 bijou sur Snow Leopard pour Rails 3 avec RVM

Question

J'ai récemment mis à niveau vers Rails 3 et créé une nouvelle application avec Rails 3.0.3, mais je continue à obtenir une erreur

 
Macintosh:$ rails server 
=> Booting WEBrick 
=> Rails 3.0.3 application starting in development on http://0.0.0.0:3000 
=> Call with -d to detach 
=> Ctrl-C to shutdown server

RuntimeError (!!! Missing the mysql2 gem. Add it to your Gemfile: gem 'mysql2'): 

J'ai 64 bits machine. Les erreurs sont seulement sur la documentation et ont semblé que la gemme a été installée correctement.

 
Macintosh:$ env ARCHFLAGS="-arch i386" gem install mysql2 -- --with-mysql-config=/usr/local/mysql/bin/mysql_config

mysql> 

C'est tout ce que j'ai dans ma toute nouvelle application, mais je reçois toujours le problème de gem mysql2 manquant.

J'ai Snow Leopard 10.6.5 avec X Code 3.2.4 installé.

Une idée?

Merci d'avance!

Answer 1

J'ai eu en fait le mauvais jeu d'adaptateurs sur mon database.yml

Ainsi, le correctif est

 
development: 
    adapter: mysql2 
    database: development_database 
    username: root 
    password: 

Au lieu de

 
adapter: mysql 

Doh!

Answer 2

Si vous voyez ce récemment, il est parce que mysql2 0,3 retiré l'adaptateur ActiveRecord, qui fait maintenant partie de Rails 3,1

WARNING: This version of mysql2 (0.3.2) doesn't ship with the ActiveRecord adapter bundled anymore as it's now part of Rails 3.1 
WARNING: Please use the 0.2.x releases if you plan on using it in Rails <= 3.0.x 

Ajustez votre Gemfile en conséquence si vous êtes sur Rails 3.0.x

gem 'mysql2', '~> 0.2.6'
