Install with errors, service fails to load

[hhackbarth]

I determined a couple of problems. It was tested with Raspbian Buster (27th May 2020) on RPi 4B:

When executing the install script, it reports:
dpkg-query: no packages found matching scons

After going through the menu items of the install script and enabling the service, it fails to start.
This is, what systemctl reports (sorry for the truncated lines):
pi@raspberrypi:~/ups3 $ sudo systemctl status smartups.service
● smartups.service - ugeek smart ups v3
Loaded: loaded (/etc/systemd/system/smartups.service; enabled; vendor

When starting the smartups.py manually, this happens:
pi@raspberrypi:~/ups3 $ /usr/bin/sudo /usr/bin/python3 /usr/local/bin/smartups.py
Traceback (most recent call last):

Hoping you can fix it soon.

Yeah, seems like the install script don't install dependencies (python packages).
Did you ever solve this?

A much better way would be to solve and install the dependencies when actually executing the install script...

try install python-pip or if you using python3 install python3-pip then modify the install script to use pip3, or set alias in bash shell
like alias pip="pip3"
