[rabbitmq-discuss] Pika AttributeError: Channel instance has no attribute 'start_consuming'

Tue May 31 19:32:03 BST 2011

Is it possible that an older version of pika is also installed in the global scope?

You could install in virtualenv to keep it local:

gmr at binti ~ $ virtualenv --no-site-packages test
New python executable in test/bin/python2.6
Also creating executable in test/bin/python
Installing setuptools............done.
Installing pip...............done.
gmr at binti ~ $ cd test/
gmr at binti ~/test $ ls
bin include lib lib64
gmr at binti ~/test $ source bin/activate
(test)gmr at binti ~/test $ pip install pika
Downloading/unpacking pika
Downloading pika-0.9.5.tar.gz
Running setup.py egg_info for package pika
Installing collected packages: pika
Running setup.py install for pika
Successfully installed pika
Cleaning up...
(test)gmr at binti ~/test $ python -c "import pika;print pika.__version__"
0.9.5
(test)gmr at binti ~/test $
