ruby / mysql mysql_adapter.rb: 505: in 'real_connect': impossible de convertir une chaîne en entier

Question

Je suis arrivé ce matin, j'ai lancé mon application de la même manière que d'habitude et j'ai commencé à avoir cette erreur. Depuis lors, j'ai parcouru tous les chemins que je peux concevoir - au point de supprimer et de réinstaller tous les logiciels Ruby / rails de ma machine, y compris mysql. J'ai réduit ma candidature à la suivante.

require 'rubygems'
require 'active_record'

class Job < ActiveRecord::Base

end

ActiveRecord::Base.establish_connection(
    :adapter     => "mysql",
    :host        => "192.168.254.22",  (I've also tried 127.0.0.1)
    :port        => "3306",
    :database    => "databasethingie",
    :username    => "root",
    :password    => "rootpassword"
)

job = Job.find (: first) C’est sur une fenêtre fonctionnant sous Instant Rail 2.0.

Je reçois toujours les erreurs:

J'ai vu des articles à ce sujet qui font référence à un bogue corrigé depuis 1.5.2 jours, mais je suis à jour. 2.1.2, etc. Que se passe-t-il ici? Je me suis demandé si cela était lié aux modifications récentes de la configuration de la base de données (octroi de tous les droits à la racine), mais la réinstallation semblerait prouver le contraire.

Avez-vous essayé:
