  note: This error originates from a subprocess, and is likely not a problem with pip.

As https://pypi.org/project/cyseq/#files does not have py3.14 files.

Even though we have python 3.14 wheels we are still failing in the same way, see https://dev.azure.com/nexB/scancode-toolkit/_build/results?buildId=17608&view=logs&j=1412dbfa-421a-5a40-8ddf-7073fc46aa19&t=a1dd25e1-87c7-5492-aaf8-91c9ef59fc48 and aboutcode-org/scancode-toolkit#4595 where we are using this.

@JonoYang any idea what could be causing this? 🤔

astral-sh/uv#7347 could be something of the same issue, but I'm not sure how to fix this.

@AyanSinhaMahapatra The cyseq builds for Python 3.14 are missing from the release on Github and pypi. I will check to see if there is an issue with the runner or something else.

[JonoYang]

@AyanSinhaMahapatra I've updated the github actions to use the latest version of cibuildwheel. I made a new release and we have 3.14 builds on pypi. I am able to use your 3.14 branch of sctk now.

[AyanSinhaMahapatra]

@JonoYang thanks a lot for resolving this. I've also released https://pypi.org/project/cyseq/0.1.2/ with a minor fix at #13
Closing!
