ComplexNetworkSim wasn't installed correctly? Or SimPy?

I tried to install ComplexNetworkSim. I followed the instructions that appear here: https://pythonhosted.org/ComplexNetworkSim/installation.html

As recommended, I used setuptools to install NetworkX and SimPy (which are prerequisites for ComplexNetworkSim).

However, when I'm trying to use the package in PyCharm, based on this example:

from ComplexNetworkSim import NetworkAgent, Sim

I get the following error message:

Traceback (most recent call last):
  File "C:/Users/Natan/PycharmProjects/final_project_Lev/solution.py", line 1, in <module>
    from ComplexNetworkSim import NetworkAgent, Sim
  File "build\bdist.win32\egg\ComplexNetworkSim\__init__.py", line 1, in <module>
  File "build\bdist.win32\egg\ComplexNetworkSim\agents.py", line 7, in <module>
ImportError: No module named SimPy

As mmdanziger suggested, I decided to give up on complexNetworkSim. Instead, I installed nxsim for Python 3 and it works just fine.

Looks like you didn't install simpy correctly. Maybe it's not in your path. Manual installations can be hard to debug. Unless there is some reason not to, you should use pip (or another package manager) for installations. Using pip you simply run:

$ pip install complexnetworksim

which leads to the output:

But that loads an out-of-date version and still might cause problems. You may want to follow the developer's advice on https://github.com/jschaul/ComplexNetworkSim and use the newer package nxsim.
