Google Raspberry pi B3 上的助手无法启动

Question

我已尝试按照本演练在我的 Raspberry pi 模型 b3 上构建 Google 助手 https://developers.google.com/assistant/sdk/prototype/getting-started-pi-python/run-sample

一切顺利，直到我尝试使用

启动它

google-assistant-demo

我得到以下堆栈跟踪

    Traceback (most recent call last):
  File "/home/pi/env/bin/google-assistant-demo", line 11, in <module>
    sys.exit(main())
  File "/home/pi/env/local/lib/python2.7/site-packages/google/assistant/__main__.py", line 66, in main
    with Assistant(credentials) as assistant:
  File "/home/pi/env/local/lib/python2.7/site-packages/google/assistant/library/assistant.py", line 86, in __init__
    self._event_queue = IterableEventQueue()
  File "/home/pi/env/local/lib/python2.7/site-packages/google/assistant/library/event.py", line 172, in __init__
    super(IterableEventQueue, self).__init__(maxsize=32)
TypeError: must be type, not classobj

我什至不知道从哪里开始，也没有尝试过任何解决方案。什么可能导致异常？

Answer 1

正如 official documentation 中指出的那样： Google 助理库当前需要 Python > 3.4。

您可以使用以下命令配置 virtual environments：

python3 -m venv env
env/bin/python -m pip install --upgrade pip setuptools
source env/bin/activate
