Package version given as 0.0.0

[Bob Kline]

The build of Python APScheduler created for the Ubuntu package incorrectly gives the version number when running in Python as 0.0.0, even though the package manager claims it has installed version 3.8.1.

$ dpkg -l | grep apscheduler
ii python3-apscheduler 3.8.1-1 all In-process task scheduler with Cron-like capabilities
$ python3 -c 'import apscheduler as a; print(a.version)'
0.0.0

In a virtual environment with the package installed using pip, the package has been built correctly, and gives the real version number from Python (as it does if I build the package by hand).

$ . venv/bin/activate
(venv) $ python3 -c 'import apscheduler as a; print(a.version)'
3.10.1

The same discrepancy is present if I use the Python builtin importlib.metadata.

The inability to query the package at runtime to determine its version prevents software from making correct decisions about how the package will behave.
