Невозможно начать единорог.

Question

Я пытаюсь запустить приложение с единорогом, но не могу начать. У меня ошибка аргумента parse_rackup_file: rackup file (config.ru) not readable (ArgumentError)

Мое окружение - rbenv ruby1.9.3 и рельсы 3.1.3.

Что случилось?

Я решил эту проблему, добавив

working_directory("/path/to/rails_root") 

внутри config/unicorn.rb

Вы можете обратиться к документации здесь: http://unicorn.bogomips.org/Unicorn/Configurator.html#method-i-working_directory
