[BUG] TypeError: canonicalize_version() got an unexpected keyword argument 'strip_trailing_zero'

[tim-s-ccs]

setuptools version

setuptools>=71.0.0

Python version

Python 3.12

OS

Ubuntu

Additional environment information

I found this bug when running the test for the project in GitHub actions

Description

When I install the requirements in my Python package project (pip-sync requirements-dev.txt) I get an error within setuptools which says:

Preparing metadata (setup.py) ... error
error: subprocess-exited-with-error

× python setup.py egg_info did not run successfully.
...
TypeError: canonicalize_version() got an unexpected keyword argument 'strip_trailing_zero'

This error was caused by using setuptools >= 71.0.0

Not to speculate but it looks like the issue was introduced by this commit in setuptools: 00384a5

And this commit is including new changes from the packaging project and its this commit here where we can see the issue:
pypa/packaging@cc938f9
https://github.com/pypa/packaging/blame/4493dfcd95a893f676a7aa4bd17c547bea676371/src/packaging/utils.py#L58

Expected behavior

I would expect pip-sync requirements-dev.txt to run successfully

How to Reproduce

Clone https://github.com/tim-s-ccs/example-python-package.git
Make sure you are using Python 3.12 and you have pip-tools installed (pip install --upgrade pip wheel pip-tools)
Make sure you are using the correct version of setuptools pip install --upgrade setuptools==71.0.0
Run pip-compile requirements-dev.in

Output

    error: subprocess-exited-with-error
    
    × python setup.py egg_info did not run successfully.

[Kaflak]

Issue is visible when you use packaging<22.0

[tonythomas01]

Could reproduce the same issue. Fixed by downgrading to 70.x

[Kaflak]

Also it can be fixed by update packaging to 22.0 or higher

[jaraco]

This behavior is by design. Similar to the issue reported in #4478, the new Setuptools 71 will prefer installed dependencies over the vendored ones. You'll want to either uninstall the older (incompatible) dependencies from the environment or install these dependencies. You may be tempted to install setuptools[core], but please avoid doing that as core is an internal implementation detail.

Just to confirm, we're seeing this happen in this environment:

python -m pip install --upgrade pip
python -m pip install --upgrade setuptools wheel twine check-wheel-contents

Is that correct? It sounds like you're saying the issue is old dependencies existing in the environment, but we should have the most current packages here.

Thanks @jaraco this was helpful. In my project where I was having the issue because on older version of packaging was a dependancy (not compatible with setuptools v71.0.0 or maybe earlier). Updating that dependancy did indeed fix the issue.

It's a bit annoying that the behaviour of setuptools changed which messed up my tests (which gets the latest version of setuptools when setting up) but that is very much my fault and not your teams.

Again, thanks for your comment as it helped my to understand the issue better and what the cause was.

---

For anyone who has a situation like me where my tests just started failing I'd check to make sure your dependancies and the dependancies of setuptools are compatible.

Thanks for posting your solution. I'm trying to reason through how we're running into the same issue. We're not specifying packaging anywhere, so I would assume we would get the most current version. And when I install locally, I get the same version of packaging you specify in your PR. Perhaps the CI image I'm using already has packaging installed, but with an older version? I'll investigate and post back if I find something. But it would definitely be a sharp corner if pip install --upgrade setuptools no longer works on ubuntu-latest.

Yes, probably.

Agreed, it is a bit of a sharp corner, and we made the major release as a signal of this shift in expectations. The issue is that while you're holding it correctly and pip install -U setuptools should theoretically upgrade all the required dependencies, it cannot currently due to the bootstrapping problem. I'm actively working on solving that issue, but in the meantime, one needs to pip install -U setuptools[core] to prepare an environment safely.

You may be tempted to install setuptools[core], but please avoid doing that as core is an internal implementation detail.

I think I may have been too cautious about this advice. We specifically want to avoid packages themselves making this declaration in build-requires. I believe it's safe to use in systems integration tooling.

@jaraco Thanks for taking the time to respond. This advice is super useful:

I think I may have been too cautious about this advice. We specifically want to avoid packages themselves making this declaration in build-requires. I believe it's safe to use in systems integration tooling.

The issue that we wound up running into is that older versions of our package actually take a runtime dependency on packaging. Upon verifying the package (by installing it), the version of packaging was getting clobbered. This was only causing an issue for the sdist, and not the wheel.

The related commit in packaging is pypa/packaging@e99b37e if anyone needs a reference (and 22.0 is correct).
