Problème pour lancer la commande rails s sur mac

Salut tout le monde,

J'apprends RoR depuis quelques semaines donc je suis pas encore super a l'aise avec la console
Je me casse les dents depuis 1h pour lancer mon serveur local. Je suis sur mac et je voudrais ouvrir social-circle-v2 (GitHub) sur chrome. J'ai enfin réussi à runer la commande $bundle install mais je trouve toujours le même problème :
from /Users/Mesnet/.rvm/gems/ruby-2.2.0/gems/spring-1.6.4/bin/spring:49:in `<top (required)>'

Donc la je sais plus trop quoi faire, si vous passez par la et que vous avez un petit tips, n'hésitez pas. Merci !

Ps: je vous mets quand même l'erreur si ça peut aider
