I installed pika for python running on a mac

More likely you are running several versions of pip and python. Check your 'pip' and 'python' versions - you should use a 'pip' version corresponding to your 'python' version:
# python --version
Python 2.7.5
# pip --version
pip 9.0.1 from /usr/lib/python3.4/site-packages/pip-9.0.1-py3.4.egg (python 3.4)
As you can see 'pip' will install modules for a python version different from the one I'm using. I used 'pip2' command for 'python2' (use pip3 for python3):
# pip2 install pika
