Can you ensure you have installed pyusb & python-uinput. You can use pip list|grep py.
You should see something like this:

...
python-uinput         0.11.2
...
pyusb                 1.2.1
...

If you don't see it here try to install it:
sudo apt install python3-uinput python-usb

After installing the required dependencies you should be able to run the install script with no errors.
Please also use the newest version!
