Ruby on Rails problème SQLite sur Windows 7 x64

Question

Lorsque je tente de faire db:create sur la base de données SQLite avec cette config db en utilisant Windows 7 x64

development: 
    adapter: sqlite3 
    database: db/development.sqlite3 
    timeout: 5000 

Je reçois cela, un peu d'erreur drôle

Couldn't create database for {"timeout"=>5000, "adapter"=>"sqlite3", "database"=>"db/development.sqlite3"} 

Answer 1

Correction en mettant sqlite3.dll dans PATH. Le problème était en fait, que Windows 7 ne m'a pas montré l'erreur à propos de la DLL manquante. Quand j'ai essayé la même chose sur Vista, j'ai eu l'erreur que sqlite3.dll n'a pas été trouvé. Mais je n'ai absolument aucune idée, pourquoi cela se produit uniquement sur Win7
