Solving dependency with uv on windows not work because of sh

[zhavir]

Somehow, I'm unable to sync my uv lock on Windows when this library is included as a dependency. The issue seems to be that it depends on the sh library, which isn't compatible with Windows. However, sh isn't listed in the pyproject.toml. Do you know if it's currently being used?

That said, when I run it as a pre-commit hook, it works like a charm. I mainly need it because I've written some plugins on top of it, and having type hinting support is really helpful.

Can confirm, here's my output:

      hint: This error likely indicates that `sh@1.14.3` depends on `fcntl`, but doesn't declare it as a build dependency.
      If `sh` is a first-party package, consider adding `fcntl` to its `build-system.requires`. Otherwise, either add it to
      your `pyproject.toml` under:

      [tool.uv.extra-build-dependencies]
      sh = ["fcntl"]

      or `uv pip install fcntl` into the environment and re-run with `--no-build-isolation`.
  help: If you want to add the package regardless of the failed resolution, provide the `--frozen` flag to skip locking
        and syncing.

I believe this is because the sh package uses fcntl which is Linux-only — gitlint pulls it in as a dependency but it can't build on Windows.

Yes, exactly! That is the issue

Any progress on this? Gitlint is effectively not compatible with Windows because of this.

@zhavir How do you set this up in an uv-based project then?

The work-around I currently have for this is using gitlint-core instead of gitlint.

[dependency-groups]
dev = [
    "gitlint-core>=0.19.1",
]

[[repos.hooks]]
id = "gitlint"
name = "gitlint"
language = "system"
entry = "uv run gitlint"
args = ["--msg-filename"]
stages = ["commit-msg"]
always_run = true

Basically I haven't add it as direct dependency of the project. I have a different file for configuration on the root folder called .gitlint. This is my pre-commit setting:

    hooks:
      - id: gitlint
        name: gitlint
        language: python
        entry: gitlint
        args: [--config=tools/gitlint/.gitlint, --staged, --msg-filename]
        stages: [commit-msg]
        additional_dependencies:
          - gitlint
