Ошибка загрузки текстуры ../../widgets/citycc0.mpg ⇐ Python

[Anonymous]

Я пытаюсь разобраться в Kivy Framework, я также новичок в Python, поэтому я действительно не могу решить это. Но в основном я пробую примеры, и каталог Kivy не работает, и я приводил это в это на терминале. Я на macOS 10.14.4, используя Python3.7. < /P>
