Ошибка удаления отладчика Gem

Я запускаю Rails v4.0.2 на Mac OS 10.9.2, и у меня все было гладко. Внезапно я получаю сообщение об ошибке, когда я пробовал rails server. Я запускаю установку пакета, и это результат:

Я очень смущен, почему эта ошибка возникла внезапно. Я работаю без проблем в течение нескольких недель. Я пробовал создать новый gemset с rvm и все еще сталкивался с той же проблемой. После поиска я сначала нашел рекомендации по обновлению зависимостей, а затем попробовал bundle install, но это не решило проблему.
