I just had the same issue with pyyaml 6.0.0

Duplicate of #723?

[mcdonnnj]

Both are duplicates of #601. This has been on the horizon for a long time apparently.

[ghost]

Yes, but I see it is again backup discussion, just 50 minutes ago !

[wesleykendall]

Yea seems like now things are going to break more loudly for others since Cython3 was released.

[AlexDld]

You can use PyYaml 5.3.1 until the issue is resolved.

[henryiii]

This has broken Python 3.12 as well; there aren't pre-built wheels for 3.12 yet (ABI is now supposed to be stable as of beta 4, so you can add them ;) )

Setting:

"pyyaml!=6.0.0,!=5.4.0,!=5.4.1", # pyyaml is broken with cython 3

Does work for now on 3.12.

[AndrewCharlesHay]

You can use PyYaml 5.3.1 until the issue is resolved.

@AlexDld Thank you! Worked for me!

[olliemath]

Affecting us too and our security policy won't let us downgrade to 5.3 because of pre-5.4 vulnerabilities

But pip install "cython<3.0.0" && pip install --no-build-isolation pyyaml==6.0 did work (as per the linked issue)

[tschaffter]

We are experiencing the same issue today with pyyaml@5.4.1. What I don't understand yet is why we were able to install this version on Friday and not today? What has changed since Friday?

On Friday:

Today: Failed to install /home/vscode/.cache/pypoetry/artifacts/b6/23/45/f5dfdd6e8ba0f620504858ddeb20b47f50b03d0c4b18f873f6575d2e78/PyYAML-5.4.1.tar.gz

[henryiii]

Cython 3.0 came out since Friday.

[johnthagen]

Cython 3 was released 4 hours ago: https://pypi.org/project/Cython/3.0.0/#history

This coincides with when our PyYAML 6.0.0 installs via Poetry in Alpine Linux containers started failing. 😢

[andy-maier]

We cannot use PyYAML 5.3 due to dependencies requiring 5.4.
On Python 3.10+3.11, using PyYAML 6.0 also works, because it provides wheel archives for these Python versions.

Is there a way to have PyYAML use Cython<3 for its installation?

[C-L-STARK]

This has broken Python 3.12 as well; there aren't pre-built wheels for 3.12 yet (ABI is now supposed to be stable as of beta 4, so you can add them ;) )

Setting:

"pyyaml!=6.0.0,!=5.4.0,!=5.4.1", # pyyaml is broken with cython 3

Does work for now on 3.12.

work for me; thanks;

[HernandoR]

based on my dependencies, i'll have to use pyyaml 5.4.1, any way to add --no-build-isolation to the pyproject.toml, so that the package management (uv in my case) can solve it?

[SamuelMarks]

"pyyaml!=6.0.0,!=5.4.0,!=5.4.1

Works on Python 2.7 also
(specifically I support 2.7, 3.5, 3.6, 3.7, 3.8, 3.9, 3.10, 3.11, 3.12, 3.13)

[sichilongom]

this worked for me
pip install pyyaml==5.3
