(<inconnu>): impossible de trouver attendu": "alors que la numérisation d'une simple clé à la ligne 3 de la colonne 1 (Psych::SyntaxError)

Je suis en train de lancer un bundle install sur un des rails de projet tiré de git. Quand je lance le bundle install j'obtiens l'erreur suivante:

    /Users/jordandeutsch/.rvm/rubies/ruby-2.2.1/lib/ruby/2.2.0/psych.rb:370:in     `parse': (<unknown>): could not find expected ':' while scanning a simple key at     line 3 column 1 (Psych::SyntaxError)

Après quelques recherches j'ai pensé qu'il pourrait être un problème avec rvm que j'ai essayé de tirer un vieux projet git et était toujours pas en mesure d'exécuter le bundle install. J'ai aussi essayé de copier un projet au niveau local et de l'exécution de l'installation et le démarrage d'un nouveau projet, le tout sans succès.

Après la réinstallation de rvm j'ai couru rvm use ruby --install --defaultet j'ai obtenu le message d'erreur suivant (similaire à ci-dessus)

/Users/jordandeutsch/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/psych.rb:370:in `parse': (<unknown>): could not find expected ':' while scanning a simple key at line 3 column 1 (Psych::SyntaxError)

Essentiellement je ne peux pas commencer un nouveau rails de projet sur l'ordinateur. Aucune information serait appréciée.
