I installed Pyomo on my Ubuntu 15.10 according to the install guide using pip install pyomo which worked fine and returned Successfully installed pyomo PyUtilib appdirs ply nose six. (I installed pip and scientific python first.)
However, if I now test it with pyomo --help, I get pyomo: command not found.
Am I missing something? Do I somehow need to add pyomo to my path?
Am I not running it correctly? In the quick start it mentioned to import pyomo.core in python. I tried that but it didn't change anything.
pip is installing into your user-writeable $HOME/.local which is very likely just missing from you $PATH and $PYTHONPATH where linux looks for scripts to execute and python looks for modules to import respectively.
Execute in a terminal session and try again:
export PATH=${HOME}/.local/bin:${PATH}
export PYTHONPATH=${HOME}/.local/lib/python2.7/site-packages:${PYTHONPATH}
If that helps, add those commands at the bottom of your $HOME/.bashrc so they get executed whenever you start a terminal session.
