This looks like a bug with https://github.com/joshvillbrandt/wireless/

It might be related to joshvillbrandt/wireless#17

If you get a chance, try reporting the error in that repo and maybe there is a workaround.

I also just pushed changes that add -s / --ssid and -i / --interface flags which should allow you to manually specify these variables, which will work around the bug with that package on archlinux.

As mentioned in the comments, cmp doesn't exist in Python 3. If you really want it, you could define it yourself:

def cmp(a, b):
return (a > b) - (a < b)

..... Or use python 2

sudo python3 wifi-users.py -i wlp3s0 -s 360WiFi-A379AF

It seems to work,but still receive a error "Error getting gateway MAC address."

[kylemcdonald]

"Error getting gateway MAC address." means that netifaces can't grab your gateway for some reason. This isn't a huge deal, because the code should still be able to detect packets that are sent to the router from other devices. But some packets only go to the gateway, and you will miss them. If you can find another way to get your gateway with Python and share it here, I'd like to add it to the script, and it will improve the quality of the results.
