尝试使用ssl连接到kafka时 kafka-python 我收到以下错误：

Traceback (most recent call last):
  File "server.py", line 23, in <module>
    kafka_producer = SimpleKafkaProducer()
  File "/my-service/kafka_producer.py", line 28, in __init__
    self.producer = KafkaProducer(**kafka_config)
  File "./ve/lib/python2.7/site-packages/kafka/producer/kafka.py", line 266, in __init__
    client = KafkaClient(**self.config)
  File "./ve/lib/python2.7/site-packages/kafka/client_async.py", line 130, in __init__
    self._bootstrap(collect_hosts(self.config['bootstrap_servers']))

    self._ssl_context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)  # pylint: disable=no-member
AttributeError: 'module' object has no attribute 'SSLContext'

我有 python v2.7.3 跑步（debian 7喘息） ssl.SSLContex 属性是从中添加的 python v2.7.9 似乎ssl支持 kafka-python 是从v1.1.0引入的，但它需要python版本>=v2.7.9，因为 ssl.SSLContext 使用。
有没有一种方法可以使用较低版本的python和ssl启动与ssl的连接 kafka-python ?
还是绕开这个？
也许有人可以推荐另一个支持到kafka的ssl连接并支持python版本=<2.7.3的包。
