raspberry-pi - SSL : CERTIFICATE_VERIFY_FAILED when trying to use the Google Assistant SDK

Question

当尝试从我的 Raspberry Pi 授权访问 Google Assistant API 时，我收到“SSLError”类型的错误，指出证书验证失败。

当我运行时:

python -m googlesamples.assistant.auth_helpers --client-secrets <path-to-secrets-file>

我得到以下跟踪:

我该如何解决这个问题？

最有可能发生这种情况的问题之一是您的日期和时间错误。如果您的时间/日期错误，请尝试:

1. 首先使用命令date ( see man page ) 手动更改日期。例如:

   sudo date -s“2017 年 4 月 24 日星期一 13:30:00 PDT”

2. 如果这有效，但您的时间始终与时间不同步，请查看 these instructions使用多种替代解决方案来确保您的时间正确同步。
