«Команда бандлера :не найдена :тонкие» рельсы развертывания героку

Таким образом, мое приложение отлично работает на моем локальном компьютере, и я успешно отправил его на github и heroku, но когда я пытаюсь открыть приложение в своем браузере, я получаю следующую ошибку:

Application Error
An error occurred in the application and your page could not be served. Please try again in a few moments.

If you are the application owner, check your logs for details.

Затем я пытаюсь запустить

$ heroku logs

И я получаю следующий вывод в своей консоли:

Я не могу понять, что с этим делать, так как это мой первый опыт развертывания на героку, и я ничего не знаю о веб-развертывании -. Любая помощь будет принята с благодарностью!
