Unable to run cap deploy:setup on ec2, the task `deploy:setup' does not exist

Я установил ruby (используя rvm), phusion passenger и все требования.

Также на ec2 я получаю сообщение об успехе при запуске $ ssh -T git@github.com

Но когда я пытаюсь запустить -> $cap deploy:setup, я получаю сообщение об ошибке задача `deploy:setup' не существует

cap -vT
