raspberry-pi - SSL: Google Assistant SDK を使用しようとすると CERTIFICATE_VERIFY_FAILED

Question

Raspberry Pi から Google Assistant API へのアクセスを承認しようとすると、「SSLError」タイプのエラーが表示され、証明書の検証に失敗したことが示されます。

私が実行すると：

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

次のトレースを取得します。

どうすればこれを修正できますか?
