05/08/2023, 3:55 PMIs there a way in pex land (rather, pants + pex land) to only package up pre-compiled python files? “Compiled” in the python bytecode sense.
This is assuming the same interpreter is doing the compiling and running of said code

05/09/2023, 1:42 PMThis should probably be guessed, but you have https://www.pantsbuild.org/docs/reference-pex_binary#codeshebangcode so just be explicit (again).

05/09/2023, 1:44 PMYep thanks, I found that again a little while ago - and by explicitly setting a python pointing at it, it works fine - I think it was more just surprise. I'm guessing it was 3.9 because Pants was using 3.9 while setting it?

05/09/2023, 1:44 PMYes.

05/09/2023, 1:51 PMI do think the docs might need to be updated here, if I"m misunderstanding this:
Set the generated PEX to use this shebang, rather than the default of PEX choosing a shebang based on the interpreter constraints.It's not choosing a default based on the interpreter_constraints when called via Pants

05/09/2023, 1:57 PMSounds like it. I'm not exactly sure why you're using ICs though since you specify target platforms.

05/09/2023, 2:01 PMOh, that's not in prod - that was just trying to see if setting that would change the 3.9 result - wasn't production code
