ERROR InvalidDistribution: Invalid distribution metadata: unrecognized or malformed field 'license-file'

Please list the steps required to reproduce this behaviour

Run 'twine upload dist/*'

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.)

[igorpompeo]

@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

[woodruffw]

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

[igorpompeo]

Sorry my delay.
Here is the .whl if isn't this, let me know please.
I really appreciated your help.

@woodruffw does this belong here or in packaging problems?

@woodruffw does this belong here or in packaging problems?

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

[woodruffw]

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.
