No se puede inicializar el servidor local para mis aplicaciones Rails

Question

Mis carriles aplicaciones han sido volviendo loco en mí últimamente. Comienzo mi servidor local mediante la ejecución de "ruby script / server" como normal. El servidor se inicia, pero cuando intento acceder a ella a través de " http: // localhost: 3000 / ", que lanza yo un error 500. Esto sucede para todas mis aplicaciones de rieles, incluso los más viejos que he dejado sin cambios desde hace varios meses. Aquí está la traza completa:

Configuración: Tengo Ruby 1.9 instala con MacPorts, y estoy corriendo en los carriles 2.3.5. Algunas cosas que he estado jugando con recientemente: - ensuciada con RVM - Probamos el Homebrew, un sistema de gestión de paquetes MacOSX - Instalado unicornio y delgada como gemas

Cualquier ayuda sería muy apreciada! Preferiría no tener que desechar mi sistema y volver a instalar todo.

Answer 1

Cuando se produce el error "constante sin inicializar", que normalmente tienen una clase o biblioteca que falta, por ejemplo, La desprotección incompleta de un proyecto o de la rama. En su caso puede haber algunos problemas con la ruta / configuración de FFI :: :: Plataforma CPU

Por cierto que está mencionando: "no tener que desechar mi sistema y volver a instalar todo" -> Yo uso al control de versiones Git mi entorno de desarrollo de vez en cuando, para que pueda obtener de la instantánea anterior antes se inició el problema.

buena suerte!
