Anything else you'd like to mention?

Sorry guys for bother y'all, but is the thing.
I'm studying python (with dummy exercises) and decide to bring a poor DevOps to my repository.
I'm using the pyproject.toml and the twine.
Mine code inside those are here: pyproject.toml
I tried another forum but I didn't get what is wrong with my codes, so if you could, check my repo, and give me some help to resolve that.

    Hi @igorpompeo, thanks for filing an issue.

    To clarify: can you share the entire error message? Are you seeing that error from twine itself, or as a spit-out from PyPI?

    (This should be fixed with packaging 25.0, which your twine metadata suggests you're using.)

    @woodruffw hello, thank you for the speed.
    For sure, this is the message of error

    Checking dist/meu_pacote_python-1.0.9-py3-none-any.whl: ERROR    InvalidDistribution: Invalid distribution metadata: unrecognized or    
         malformed field 'license-file'

    This error appears to me at the verify file step at my CD

    Okay, thank you. Could you share that .whl file, as well as the output you see when you run pip list?

    Sorry my delay.

    I really appreciated your help.

    @woodruffw does this belong here or in packaging problems?

    My packaging are at version 25.0, I had checked. Sorry for intruding

    Hmm, I can't reproduce this: I extracted the METADATA file from that .whl, and it parses fine:

    uv run --with packaging python

    then:

    >>> from packaging.metadata import Metadata
>>> email = open("./METADATA").read()
>>> meta = Metadata.from_email(email)
>>> meta.license_files
['LICENSE']

    @igorpompeo can you please provide your full pip list output? I strongly suspect you're running into some kind of mixed environment problem.

    (Per @sigmavirus24's point, this is probably best suited for general triage in packaging-problems, so I'll migrate there.)

    Thanks, I'll be able to triage this more tonight.

    Yes, that's helpful context, thanks! That's the right thing to be doing.

    Sorry about that, I'm new in all of this.
