          And because only transitive-package-only-prereleases-in-range-a==0.1.0 is available and you require transitive-package-only-prereleases-in-range-a, we can conclude that your requirements are unsatisfiable.

          hint: Only pre-releases of `transitive-package-only-prereleases-in-range-b` (e.g., 1.0.0a1) match these build requirements, and build environments can't enable pre-releases automatically. Add `transitive-package-only-prereleases-in-range-b>=1.0.0a1` to `build-system.requires`, `[tool.uv.extra-build-dependencies]`, or supply it via `uv build --build-constraint`.

      × Failed to build `sklearn==0.0.post12`
      ├─▶ The build backend returned an error
      ╰─▶ Call to `setuptools.build_meta:__legacy__.build_wheel` failed (exit status: 1)

          [stderr]
          The 'sklearn' PyPI package is deprecated, use 'scikit-learn'
          rather than 'sklearn' for pip commands.

          Here is how to fix this error in the main use cases:
          - use 'pip install scikit-learn' rather than 'pip install sklearn'
          - replace 'sklearn' by 'scikit-learn' in your pip requirements files
            (requirements.txt, setup.py, setup.cfg, Pipfile, etc ...)
          - if the 'sklearn' package is used by one of your dependencies,
            it would be great if you take some time to track which package uses
            'sklearn' instead of 'scikit-learn' and report it to their issue tracker
          - as a last resort, set the environment variable
            SKLEARN_ALLOW_DEPRECATED_SKLEARN_PACKAGE_INSTALL=True to avoid this error

          More information is available at
          https://github.com/scikit-learn/sklearn-pypi-package

          hint: This usually indicates a problem with the package or the build environment.
      help: `sklearn` is often confused for `scikit-learn` Did you mean to install `scikit-learn` instead?
