How to exclude transitive sub dependencies?

[jm-nab]

Is there a way to explicitly exclude transitive sub dependencies?

Say for example I have in my dependencies:

• super-spam

And super-spam has a dependency:

• sub-spam-dont-use
• main-spam

If I do pip install -e . via the pyproject.toml in my own project, is there a way to exclude installing sub-spam-dont-use?

I've tried:

• sub-spam-dont-use != *
• a custom build hook, where i tried to override dependencies, but i didn't get it working
• a custom path based build with a stubbed repo which just fakes the transitive dependency

The hack that I have been using is:

pip install . && pip uninstall sub-spam-dont-use

But it seems off since its not part of pyproject.toml.

class CustomBuildHook(BuildHookInterface):
    def dependencies(self, version: str, build_data: dict[str, Any]) -> None:
        # List of dependencies to remove (stub out or ignore)
        ignored_dependencies = [
            'sub-spam-dont-use',
        ]
        # Get the current list of dependencies from the build data
        print(build_data)
        print(build_data)
        print(build_data)
        print(build_data)
        current_dependencies = build_data.get("dependencies", [])
        logging.info(f"Current dependencies: {current_dependencies}")

        # Filter out dependencies that should be ignored
        modified_dependencies = [
            dep for dep in current_dependencies if dep.name not in ignored_dependencies
        ]

        # Update the build data with the modified dependencies
        build_data["dependencies"] = modified_dependencies
        return build_data
