Не удается установить библиотеку Google Assistant на Raspberry Pi 3 Model B
Я пытался установить библиотеку Google Assistant на Raspberry Pi 3 Model B, работающей под управлением Raspbian Stretch с рабочим столом, сентябрь 2017 года, следуя руководству: Загрузите библиотеку и запустите образец.
Я успешно создал виртуальную среду Python. Однако я не смог установить библиотеку. Журнал выглядит следующим образом:
$ python -m pip install --upgrade google-assistant-library
Collecting google-assistant-library
Exception:

Я пробовал это в нескольких разных сетевых средах, но результаты не изменились. Если у вас есть какие-либо советы по этому вопросу, пожалуйста, дайте мне знать.
