En el modo de producción obtengo - No hay tal archivo para cargar - ruby-debug (LoadError)

Question

Estoy utilizando Rails 3.2.1 y la línea 'ruby-debug19' ha sido comentada en el Gemfile. Cuando inicio el servidor en modo de desarrollo, el servidor se inicia sin ningún problema. Sin embargo, cuando se inicia mi servidor en modo de producción (carriles servidor de producción -e, que endup consiguiendo el error siguiente (véase seguimiento de la pila siguiente):

... `rescue in depend_on': No such file to load -- ruby-debug (LoadError) 

he pasado muy poco tiempo tratando de averiguar quién es requiriendo re-depuración sin suerte. No estoy seguro de qué incluir, excepto mi Gemfile y la pila. Realmente agradecería cualquier ayuda.

Una pieza más de información: la línea 5 en mi archivo environment.rb solo está llamando "Aplicación .initialize "

Gemfile:

Su Gemfile.lock puede ayudar a rastrear el cual gem tiene ruby-debug como una dependencia. Ábrelo y busca 'ruby-debug' y debe estar anidado debajo de la gema que depende de él.

Dicho esto, me doy cuenta de un problema que puede causarle un poco de dolor. La gema aws-s3 y las gemas aws-sdk no son compatibles. Ambos usan la constante AWS :: S3, uno como módulo y el otro como clase. Obtienes diferentes comportamientos dependiendo del orden en que se requieren.

Paperclip reemplazó recientemente aws-s3 como una dependencia con aws-sdk. Debería poder eliminar simplemente aws-s3 de su Gemfile (a menos que use específicamente aws-s3 fuera del clip). Si depende de aws-s3 fuera del clip, querrá reemplazar esas llamadas con llamadas equivalentes usando aws-sdk.
