apscheduler: PyInstaller fails to package APScheduler various `pkg_resources.DistributionNotFound`

Describe the bug When using PyInstaller to compile an executable python application containing apscheduler the application fails to add all of apschedulers dependencies…

It seems that the apscheduler code is making some “on the run imports” and therefore PyInstaller does not find the packages it needs to integrate. Similar to 131.

Pyinstaller executable package can be configured using a “hook files” but I can’t determine which imports are required…

Running the executable raises various pkg_resources.DistributionNotFound errors. What is strange is that running the same executable multiple times raises different exceptions.

To Reproduce Working on this now… https://github.com/iamliamc/pyinstaller_apscheduler_test

Expected behavior Python standalone application works fine. Expect compiled version to run similarly.

As 131 describes I have tried switching over to explicit trigger declarations like:

        self.scheduler.add_job(
            self.restore_defaults.__call__,
            id="RestoreDefaults",
            trigger=IntervalTrigger(
                start_date=self.scheduler.calc_start_for_interval_minutes(self.start_offset) + dt.timedelta(minutes=60),
                seconds=600,
            )
        )
