Impossible d'initialiser le serveur local pour mes applications Rails

Question

Mes applications sur les rails ont récemment flippé sur moi. Je démarre mon serveur local en exécutant "script/serveur ruby" comme d'habitude. Le serveur démarre, mais quand j'essaie d'y accéder via "http://localhost:3000/", il me jette une erreur de 500. Cela arrive pour toutes mes applications de rails, même les anciennes que je n'ai pas modifiées depuis plusieurs mois maintenant. Voici la trace complète:

Configuration: J'ai Ruby 1.9 installé avec MacPorts, et je suis sur des rails 2.3.5. Certaines choses que j'ai joué avec récemment: - sali avec RVM - Nous avons essayé le Homebrew, un système de gestion des paquets MacOSX - comme des pierres précieuses Licorne et mince installé

Toute aide serait grandement appréciée! Je préférerais ne pas avoir à mettre au rebut mon système et à tout réinstaller.

Answer 1

Lorsque j'obtiens l'erreur "constante non initialisée", j'ai normalement une classe ou une bibliothèque manquante, par ex. une extraction incomplète d'un projet ou d'une succursale. Dans votre cas, il peut y avoir quelques problèmes avec le chemin/configuration de FFI :: Platform :: CPU

BTW vous mentionnez: "ne pas avoir à mettre mon système et tout réinstaller" -> J'utilise git à la version Contrôler mon environnement de développement de temps en temps, donc je peux vérifier l'instantané précédent avant que le problème ne commence.

bonne chance!
