Получение ошибки при компиляции приложения с Py2app на Python 2.7 (поднять ImportError («Без имени модуля» + qname))

Я нахожусь на Mac 10.14, Python 2.7 (установлен из двоичного файла, загруженного с https://www.python.org), работающего из /Library/Frameworks/Python.framework/Versions/2.7/bin/python. У меня установлена py2app, последняя версия, но при попытке скомпилировать приложения я получаю следующую ошибку:

Я не могу найти, что здесь не так. Любые предложения, пожалуйста?
