Cannot Import Neuron Module into PyCharm

I am having a problem importing a module name Neuron into PyCharm. I am running MacOS Sierra.

"~ which python" in the terminal generates the output:

/Users/billycarson/anaconda/bin/python

Showing that I'm using Anaconda 2.7 as the default Python. Entering the commands:

python

import neuron

into the terminal returns the output:

Python 2.7.13 |Anaconda custom (x86_64)| (default, Dec 20 2016, 23:05:08)

[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.57)] on darwin

So this shows that Python can import the module Neuron. I checked which Python I was using as my PyCharm project interpreter and it was Anaconda 2.7. However, when I type "from neuron import h, gui" into a script and run said script, PyCharm returns an error saying "No module named neuron".

What am I doing wrong/how can I fix this problem? Why does Python/Anaconda recognize the module but PyCharm does not?
