Я пытаюсь развернуть mailman с демоном и capistrano для моего приложения rails в рабочей среде, но получаю эту ошибку на своем локальном компьютере:

SSHKit::Runner::ExecuteError: Exception while executing on host 173.63.11.34: Exception while executing on host 178.62.16.69: script/mailman_daemon.rb exit status: 127

И ниже мой гемфайл:

Я использую capistrano (3.4.0) и capistrano-rvm (0.1.2).

И я попытался использовать гем rvm1-capistrano3 и rvm-capistrano, как это предлагается в этом thread, но не повезло.

Может ли кто-нибудь помочь?

Спасибо!
