Trying to produce a binary with

pants.backend.experimental.python.packaging.pyoxidizer

and hitting an issue with argsparse. I’ve been able to successfully run

pants package

, but when running the resulting binary I get an error that seems to stem from the use of

argsparse

❯ dist/src.python.mdevxp.code_ownership/code-ownership/aarch64-apple-darwin/debug/install/code-ownership
Traceback (most recent call last):

TypeError: expected str, bytes or os.PathLike object, not NoneType

The same entry point works with pex. If I replace my entrypoint to a hello_world.py script within the same pants package, it works, so it seems like something is not being configured correctly between pyoxidizer and what argsparse expected. Before I go down that rabbit hole, was wondering if anyone has already hit and solved this issue.

Related? https://github.com/indygreg/PyOxidizer/issues/307 PyOx strips the sys.argv (argv[0]), or something equally wonky

Maybe this helps?

That did it. Thanks.
