Error getting Scapy to work on Windows: "'module' object has no attribute 'ex_name'"

Question

I'm trying to run a Python script that involves ARP sniffing and is apparently dependent on the Scapy library being present. I have absolutely no idea what I'm doing but I'm reasonably good at Googling, following directions, and copying/pasting. I have it up and running on my Mac, but I'm stuck on what I hope is the last hurdle in getting Scapy working on my Windows computer (which is ultimately the one that needs to be running this script).

I followed all of the instructions at http://www.secdev.org/projects/scapy/doc/installation.html#windows, except that I chose Python 2.7 and used the newer 2.7-compatible versions of everything listed there. I used “python setup.py install” (successfully, as best I could tell) on all installs except Pypcap and Libdnet, which I installed via the Exe as an Administrator as instructed.

Unfortunately, when I type "scapy" into the command prompt to test if it works, I get the following information & error message:

C:\scapy-2.3.1>scapy
INFO: Can't import python gnuplot wrapper . Won't be able to plot.
INFO: Can't import PyX. Won't be able to use psdump() or pdfdump().

    win_name = pcapdnet.pcap.ex_name(guess)
AttributeError: 'module' object has no attribute 'ex_name'

Can anyone help me out? If you need more information please let me know.

I am running Windows 10.

Thanks in advance, - Ethan
