Summary

pkg_resources was removed from setuptools 82.0.0 (PEP 740, Feb 2026). This breaks uvloop installation when built from source with the latest setuptools.

Fix

Replace pkg_resources.Requirement.parse() with the stdlib packaging.requirements.Requirement (available since Python 3.8):

• Removed: import pkg_resources
• Removed: pkg_resources.Requirement.parse(CYTHON_DEPENDENCY)
• Added: from packaging.requirements import Requirement
• Added: Requirement(CYTHON_DEPENDENCY)

The version comparison is updated to use specifier string comparison.

Testing

pip install setuptools>=82
pip install uvloop # should work without pkg_resources error
python -c "import uvloop"

Fixes #729
