Remove support for installed .egg distributions when using the importlib.metadata backend

[sbidoul]

pip has dropped support for installing .egg distributions when it stopped invoking setup.py install.
At some point pip will abandon support for detecting and uninstalling legacy .egg distributions too.

If you reach this issue from the pip deprecation message, it is likely that your Python environment has distributions that have been installed with setup.py install, easy_install, or an older pip version.

The recommended action is to uninstall the distribution and reinstall it with a recent pip.

@hanivianka have you tried the recommended action mentioned in the top post of this page?

@sbidoul has pip 24.3 been released? im tired of seeing the bright message pop up on an otherwise dark screen

[sbidoul]

@tahayparker 24.3 is planned for October 2024.

It is important that affected users resolve the warning by applying the recommendation in the first post of this page.

Hello sir, could you please do me a favor? the picture below is the content of my file

I ran "python setup.py install", but after that there is something wrong. You can see it below:

What should I do? I would appreciate it for your kindness. Thank you anyway.

The problem is based on PIP updating. update to 23.3.2, rebuild the build.

first, delete the build and the dist plus the .egg.info folder.
rm -rf build dist *.egg.info

build build:

python3 -m pip install --upgrade build
python3 -m build

then, the twine:

python3 -m pip install --upgrade twine
python3 -m twine upload dist/*

What should I do? Please Help someone

@jdu211171 at first glance it seems like a distro level install is broken

Please report this to your distro

mamba run pip install -U smp build twine

Nice to see that NGC containers e.g. https://catalog.ngc.nvidia.com/orgs/nvidia/containers/pytorch/tags have this problem still.

Hi, I'm the maintainer of py2app and have an issue a user that runs into this change when bundling pip as part of an application packaged with py2app. Py2app bundles the used bits of the standard library and other packages used by the app (in this case including pip) into a zip file in the macOS app bundle.

Do you have any hints on what might trigger the .egg detection for this use case?

@ronaldoussoren it might be you are hitting pkg_resources.find_eggs_in_zip, which seems to look for .egg-info metadata directories. Do you have those in the bundle?

@sbidoul We do not have .egg-info dirs in the .zip file, if that's what you mean. The .zip file is on sys.path.

The warning we're seeing is this:

DEPRECATION: Loading egg at /Users/just/code/git/drawbot/dist/DrawBot.app/Contents/Resources/lib/python312.zip is deprecated. pip 25.1 will enforce this behaviour change.

DEPRECATION: Loading egg

Followup: the zip file does contain these kinds of entries:

• modulename
• modulename-0.2.3.dist-info

If I remove the .dist-info folder, the warning goes away.

[uranusjr]

Hmm, I’m not even sure loading .dist-info from a zip is even an intended feature, or if we want to continue support it or not. The warning (and the wholde deprecation) is supposed to only apply to loading .egg-info from a zip. We should have a separate issue to discuss this.
