Hello everyone! Quick question: I have poetry dependencies in a pyproject.toml (at root level), my target depends on

python-magic

and the module it exposes is just

magic

. I checked the Module Mapping docs, however I don't understand how to use it. I expect to declare in the root BUILD file that such mapping exists

poetry_requirements()

python_requirement(
    module_mapping={"python-magic": ["magic"]}
)

But I get a MappingError

Targets in root-level BUILD files must be named explicitly.

I think you're on the right track... but does the python-magic requirement come from your poetry requirements spec ?

The error in particular above, comes from that you have an unnamed target in your root BUILD file. Simply add

name=…

to it, like:

python_requirement(name="my-requirement", ...)

oh I see! i'll try right now

poetry_requirements is a macro, so it should pick up its name some other way

it does indeed work! thanks, i do understand how it works now!

poetry_requirements is a macro, so it should pick up its name some other way

yea, that macro (and

python_requirements

) are both magical right now: there will be magic removal as part of #12915
