В настоящее время я пытаюсь запустить свой тестовый набор в терминале, но я получаю следующую ошибку:

Missing required arguments: aws_access_key_id, aws_secret_access_key (ArgumentError)

Я использую Carrierwave в своем проекте, и я почти уверен, что именно это является причиной проблемы. вот мой конфиг / инициализаторы / carrierwave.rb:

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',                       
    :aws_access_key_id      => ENV['S3_ACCESS_KEY_ID'],                        
    :aws_secret_access_key  => ENV['S3_SECRET_ACCESS_KEY']
  }
  config.fog_directory  = 'my_directory'                    

end

Вот мой журнал:

Что мне нужно сделать, чтобы избавиться от этой ошибки и запустить мои тесты?
