[solved] Hi 👋 I am new to pants and struggle setting up the target for the following scenario: a shell script that calls a python module (

python -m module

) and the "catch" is that the python interpreter must not be the default one. What I have tried to do is the following:

shell_source(
    source="./my-script.sh",
    dependencies=[
        "//tools/pants/dev:dev_env_export",
    ]
)

python_sources(
    name="dev_env_export",
    interpreter_constraints=["CPython==3.9.*"],
    resolve = "dev-pants",
    dependencies=[
        "//tools/pants/dev:dev-pants",
    ]
)

pants_requirements(
    name = "dev-pants",
    resolve = "dev-pants"
)

However,

pants_requirements

gets processed with the default interpreter (Py312), which then fails. What's the right way to make

pants_requirement

use Py39? Thanks 🙏

I think you need this one https://www.pantsbuild.org/2.20/reference/subsystems/python#resolves_to_interpreter_constraints

Yes, that's it. Thanks a lot!
