DEPRECATION: Legacy setup.py install is deprecated. pip 24.1 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of <pkg> or contact the author to suggest that they release a PEP 517 build backend.

Root Cause

The package ships only a legacy `setup.py` without `pyproject.toml`, so pip must invoke `setup.py install` instead of a PEP 517 backend.

中文

该包仅提供旧式 `setup.py` 而缺少 `pyproject.toml`，因此 pip 必须调用 `setup.py install` 而非 PEP 517 后端。

Workarounds

  1. 85% success 
    Pin a version that has migrated to pyproject.toml, or vendor the source and add a minimal pyproject.toml with `[build-system] requires=['setuptools>=61'] build-backend='setuptools.build_meta'`.
  2. 70% success 
    Silence locally with `PYTHONWARNINGS=ignore::DeprecationWarning` for CI noise only (does NOT fix the underlying issue).

Dead Ends

Common approaches that don't work:

  1. 85% fail

    The deprecation is about the missing PEP 517 metadata, not build isolation.

  2. 60% fail

    If the upstream project has not yet migrated, the newest release still triggers the same deprecation.
