env:centos，python2.7.9Kafkapython==0.9.3六==1.9.0
我是新来Kafka，我只是尝试一个例子程序和下面的错误。任何帮助都将不胜感激。代码在“from kafka import kafkaclient，keyedproducer，roundrobinpartitioner”中引发错误

Traceback (most recent call last):

    from kafka import KafkaClient, KeyedProducer, RoundRobinPartitioner

如果我尝试“pip install distribute”，

Exception:
