ImportError: attempted relative import with no known parent package

[cyrax72]

Hi. I run the application like this:
/home/pi/modbus2mqtt/bin/python3 -m modbus2mqtt --rtu /dev/ttyUSB0 --rtu-baud 9600 --rtu-parity none --mqtt-host localhost --config /home/pi/modbus2mqtt/example.csv

I get this error:

Traceback (most recent call last):
File "", line 198, in _run_module_as_main
File "", line 88, in _run_code
File "/home/pi/modbus2mqtt/lib/python3.11/site-packages/modbus2mqtt/modbus2mqtt.py", line 44, in
from .addToHomeAssistant import HassConnector
ImportError: attempted relative import with no known parent package

the library versions are as follows:

/home/pi/modbus2mqtt/bin/pip3 list

Please tell me what is wrong and how to fix it? probably some libraries of the wrong version?
