Comment:
Replying to [ticket:34787 Joël Larose]:
> It gives:
> {{{
> <project_path>\venv\Scripts\python.exe: Error while finding module
specification for '__main__' (ValueError: __main__.__spec__ is None)
> }}}
>
> After much debugging and tracing, I found where the issue lies. The
problem is in the `get_child_arguments` function in
`django/utils/autoreload.py`. When you flip the first two `if`-`elif`
blocks, everything works. That is, the check for `not py_script.exists()`
needs to come before the check for `getattr(__main__, "__spec__", None) is
not None`.
Can you provide the full stacktrace? I'm not sure how swapping these
branches can make a difference as the first one is protected against
`None` `__spec__`.
