SSL: certificate_verify_failed 使用 Google Assistant SDK

Question

我正在尝试让 google assistant sdk 示例在 pi 上运行，但在收到授权 URL 后使用

google-oauthlib-tool --client-secrets /home/pi/client_secret_<my-id>.json --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless

我从提供的 url 输入代码并得到这个转储:

我检查了this post它有类似的问题并相应地更新了我的时钟，但这似乎不是问题所在。我已经重新下载了所有的库和工具，并确保 python 是最新的，但我无法让它工作。这个问题有解决办法吗？

同样值得注意的是，无论我输入什么作为授权码，都会发生同样的跟踪，即使只是输入“x”也会产生相同的输出。

Answer 1

我按照 https://developers.google.com/assistant/sdk/develop/python/run-sample 上的说明进行操作但我认为这些说明忘记了步骤:

sudo apt-get install portaudio19-dev libffi-dev libssl-dev

这样做然后重新运行 google-oauthlib-tool 就成功了。
