Summary

I would like to request the ability to configure the no-install-package option directly in the pyproject.toml file for uv. This would allow users to persistently exclude specific packages from installation when running uv sync, without needing to pass the --no-install-package flag every time.

Motivation

Currently, the --no-install-package flag must be provided as a command-line argument, which can be inconvenient for projects that frequently need to exclude certain packages (e.g., platform-specific dependencies or optional packages). Adding support for this configuration in pyproject.toml would:

• Improve developer workflow by reducing repetitive command-line options.
• Allow teams to share consistent exclusion rules across environments via version-controlled configuration files.
• Enhance flexibility and usability of uv for complex dependency management scenarios.

Proposed Solution

Introduce a new configuration option under [tool.uv] in pyproject.toml, such as:

[tool.uv]
no-install-packages = ["package1", "package2"]

When uv sync is run, any packages listed under no-install-packages would be excluded from installation automatically.

Example Usage

1. Add the following to pyproject.toml:

   [tool.uv]
   no-install-packages = ["example-package", "another-package"]

2. Run uv sync. The specified packages would be excluded from installation without requiring additional flags.
