Root Cause

The project still uses the deprecated setup.py install path and namespace_packages keyword, which setuptools has deprecated in favor of PEP 420 native namespace packages and pyproject.toml-based builds.

generic

中文

项目仍使用已弃用的 setup.py install 路径和 namespace_packages 关键字，setuptools 已弃用它们，推荐使用 PEP 420 原生命名空间包和基于 pyproject.toml 的构建。

Workarounds

  1. 85% success 
    # remove namespace_packages from setup.cfg/setup.py
# rely on implicit namespace packages:
# mypkg/sub/__init__.py (implicit, no __init__ needed at mypkg level)
pip install -e .
  2. 90% success 
    python -m pip install build
python -m build
pip install dist/*.whl

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Suppresses warnings but the deprecated code path still runs and will be removed in future setuptools releases.

  2. 80% fail

    Avoids the warning but blocks security fixes and breaks on Python 3.12+ where distutils is gone.
