我创建了一个 nameko 服务，可以向提供的电话号码发送短信。使用Africas Talking API。该服务成功运行，但是一旦您使用 nameko shell，它就无法工作。但是，电话号码已成功传递到服务中。

名子壳：

 >>> n.rpc.sms.text('+254712619789')
    Traceback (most recent call last):
      File "<console>", line 1, in <module>
      File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/nameko/rpc.py", line 369, in __call__
        return reply.result()
      File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/nameko/rpc.py", line 327, in result
        raise deserialize(error)
    nameko.exceptions.RemoteError: TypeError GreenSSLSocket does not have a public constructor. Instances are returned by SSLContext.wrap_socket().

问题可能是 eventlet 与 python 3.7 不兼容。你能用python 3.6试试吗？

（参见例如https://github.com/eventlet/eventlet/issues/502）
