Impossible de charger l'application Rails avec un bourrelet bourru

Question

J'essaie de charger une application Ruby on Rails qui utilise le Gruff gem. Je peux charger Gruff bien dans irb, mais chaque fois que j'essaie de charger l'application (via ruby script/server), il se bloque. Voici la trace complète de la pile:

Comment puis-je résoudre ce problème si l'application fonctionnera?

Answer 1

La gemme doit-elle être installée directement dans l'application de votre rail?

De here:

Rails Plugin

Gruff est facile à utiliser avec Rails.

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

Si vous avez seulement fait gem install gruff cela pourrait expliquer ne pas travailler dans des rails, mais travaillant dans RIR.
