[rabbitmq-discuss] First Python sample (send.py) gives error: AttributeError: 'ProtocolHeader' object has no attribute 'channel_number'

[xdnny]

Hello,

well, for me it doesn't work.

OS: Scientific Linux 6.2 - 2.6.32-220.4.1.el6.i686 (RHEL)
Python: 2.6.6
Pika: 0.9.5
RabbitMQ: rabbitmq-server-2.6.1 (also tried rabbitmq-server-2.7.1 from
rabbitmq.com)

After running an example "send.py" from https://www.rabbitmq.com/tutorials/tutorial-one-python.html,
here is the error:

AttributeError: 'ProtocolHeader' object has no attribute
'channel_number'

Full stack trace:

python send.py
