IoT Python SDK在Raspberry Pi上是否存在问题？

【以下的回答经过翻译处理】 我正在按照以下教程逐步设置树莓派，以便在家中进行物联网项目。 https://docs.aws.amazon.com/iot/latest/developerguide/connecting-to-existing-device.html 我已经多次阅读了教程，并且非常确定我在AWS IoT网站上为物联网设备正确设置了证书和策略。 然而，当我尝试运行pubsub.py示例时，出现了错误： Traceback (most recent call last): File "/home/pi/aws-iot-device-sdk-python-v2/samples/pubsub.py", line 113, in <module> mqtt_connection = mqtt_connection_builder.mtls_from_path( File "/home/pi/.local/lib/python3.9/site-packages/awsiot/mqtt_connection_builder.py", line 231, in mtls_from_path return _builder(tls_ctx_options, **kwargs) File "/home/pi/.local/lib/python3.9/site-packages/awsiot/mqtt_connection_builder.py", line 189, in _builder tls_ctx = awscrt.io.ClientTlsContext(tls_ctx_options) File "/home/pi/.local/lib/python3.9/site-packages/awscrt/io.py", line 424, in init self._binding = _awscrt.client_tls_ctx_new( RuntimeError: 1033 (AWS_IO_TLS_CTX_ERROR): Failed to create tls context 同样地，当我尝试运行shadow.py示例时，出现了相同的错误。 在这个项目中，我只是想告诉Alexa打开一个设备，并让它切换GPIO引脚的开关状态。非常简单，但目前似乎Python SDK出现了问题。至少，可能是最新版本和树莓派的兼容性问题。

我尝试在我的树莓派4上复现这个问题。在我的环境中，使用Python 3.7.3、awscrt 0.12.1和awsiotsdk 1.7.1，教程按预期工作。 pi@raspberrypi:/aws-iot-device-sdk-python-v2 $ pip3 show awscrt Name: awscrt Version: 0.12.1 ... pi@raspberrypi:/aws-iot-device-sdk-python-v2 $ pip3 show awsiotsdk Name: awsiotsdk Version: 1.7.1 ... 另外，根据您分享的错误信息，我看到您正在使用Python3.9进行测试，所以我下载并安装了Python3.9来模拟您的环境。同样地，教程按预期工作。我将分享我的测试输出以帮助您进行故障排除。PS：我用字符掩盖了一些标识符。 pi@raspberrypi:/aws-iot-device-sdk-python-v2/samples $ python3.9 --version Python 3.9.9 pi@raspberrypi:/aws-iot-device-sdk-python-v2/samples $ pip3.9 freeze awscrt==0.12.1 awsiotsdk==1.7.1 pi@raspberrypi:~/aws-iot-device-sdk-python-v2/samples $ python3.9 pubsub.py --topic topic_1 --root-ca ~/certs/AmazonRootCA1.pem --cert ~/certs/-certificate.pem.crt --key ~/certs/**-private.pem.key --endpoint **-ats.iot.eu-west-1.amazonaws.com Connecting to -ats.iot.eu-west-1.amazonaws.com with client ID 'test-'...
