Root Cause

Running `python setup.py install` directly. Modern setuptools emits a DeprecationWarning and eventually will remove direct install support in favor of PEP 517 builds.

generic

中文

直接运行 `python setup.py install`。新版 setuptools 会发出弃用警告，并最终移除直接安装支持，改用 PEP 517 构建。

Workarounds

  1. 98% success 
    Use pip to install the project in editable or normal mode: python -m pip install . or python -m pip install -e .
  2. 95% success 
    Build a wheel then install it: python -m pip install build && python -m build && python -m pip install dist/*.whl

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Hides the warning but the install path is still deprecated and may produce a broken egg-info layout.

  2. 80% fail

    Pins to an old setuptools that lacks PEP 517 support and breaks other modern packages.
