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

[Marek Majkowski]

Matt,

Looks like you have a wrong version of pika.

Are you sure you have pika 0.9.5 exactly?

Have you installed it as suggested on the tutorial page, using pip:
   pip install -e git+http://github.com/pika/pika.git@v0.9.5#egg=pika-v0.9.5

Cheers!
  Marek
