Can someone test

./pants run

on a

pex_binary

with ``use_deprecated_pex_binary_run_semantics` set to

false

? Try it with

layout

set to

packed

. I'm seeing

Error executing interactive process: Permission denied (os error 13)

but can't repro in a sandbox. I suspect we might need more logic to invoke the PEX with

python

?

i repro with

packed

I'm on mobile, feel free to beat me to filing an issue and/or fixing before I'm back tomorrow

filed https://github.com/pantsbuild/pants/issues/16562 … i need to do https://github.com/pantsbuild/pants/issues/16325 first, but will look at it afterwards

https://github.com/pantsbuild/pants/blob/main/src/python/pants/backend/python/goals/run_pex_binary.py#L34 There's the code

For packed (or loose) you can alternately run with either

python pex/

or

./pex/__main__.py

I think running with

python

<PEX>

would make the code layout agnostic which is nice
