Ошибка при запуске при использовании Spork и Guard

Вот проблема. При добавлении Guard gem все было нормально, когда я звонил Guard. Когда я добавил Spork, я получаю следующую ошибку, которая не влияет на тестирование моих тестов, но она поднимает ее каждый раз, когда я пытаюсь перезапустить Guard.

19:01:28 - INFO - Guard uses TerminalTitle to send notifications.
19:01:28 - INFO - Starting Spork for RSpec
19:01:28 - ERROR - Guard::Spork failed to achieve its <start>, exception was:
