No se puede cargar la aplicación Rails con gema áspera

Question

Estoy intentando cargar una aplicación Ruby on Rails que utiliza la Gruff gem . Puedo cargar Gruff bien en irb , pero cada vez que intento cargar la aplicación (a través de ruby ??script / server ), se bloquea. Aquí está el seguimiento completo de la pila:

¿Cómo puedo solucionar esto para que la aplicación se ejecute?

Answer 1

¿Es necesario instalar la gema directamente en el directorio de la aplicación rails?

Complemento Rails

     

Gruff es fácil de usar con Rails.

gem install gruff
cd vendor/plugins && gem unpack gruff

Si solo ha hecho gem install gruff , esto podría explicar que no funciona en rails sino en irb.
