требуют: нет такого файла для загрузки - test_helper (LoadError) происходит только в производстве, а не в разработке

Question

Я новичок в Ruby on Rails и после руководства по Ruby On Rails от Michael Hartl. Я нахожусь в главе 9, и все отлично работает в разработке - все тесты проходят, и я могу открывать и перемещать приложение. Однако, когда я пытаюсь открыть в производстве (Heroku), приложение аварийно завершает работу. Вот сообщение об ошибке консоли Heroku:

я получаю такое же сообщение, если я пытаюсь

rails s -e production 

Я подтвердил, что мой файл test_helper.rb действительно в моей тестовой папке. Любая помощь оценивается.

Answer 1

Это удар в темноте, но вам нужно, чтобы ваш test_helper находился где-то еще в вашем приложении? От чтения backtrace кажется, что вы требуете его в app/app/helpers/sessions_helper_test.rb.

Кроме того, app/app/ выглядит рыбным. У вас есть папка приложения внутри папки вашего приложения? Это тоже может быть проблемой.
