Ruby on rails - Bundler version 1.5.1 est requis ; vous êtes en cours d'exécution 1.2.1. Peut-être essayer « gem install bundler - v 1.5.2 » - Stack Overflow

Bundler version 1.5.1 is required; you're currently running 1.2.1. Maybe try `gem install bundler -v 1.5.2`.

Please Help me to solve this issue. Thanks.
