Cannot find Xlib

[XeroShi]

So attempting to run it on my Mac it keeps on giving me this.
Traceback (most recent call last):
File "/Users/(MacName)/3DSController.py", line 6, in
import Xlib, Xlib.display, Xlib.XK
ModuleNotFoundError: No module named 'Xlib'
What does this mean?

Use in a Terminal:

pip install Xlib

Or:

easy_install Xlib

I got this error after install Xlib via pip then run 3DSController.py

Running via Termux!

$ ./3DSController.py
