Error with importlib.metadata using python version 3.7.3

[agengr1293]

I am using an older version of Raspian and I keep getting stuck on this step.

After running python3 src/system_sensors.py src/settings.yaml

I get this error
Traceback (most recent call last):
File "src/system_sensors.py", line 12, in
import importlib.metadata
ModuleNotFoundError: No module named 'importlib.metadata'

Can you assist?
