根因分析

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。

English

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

解决方案

  1. 85% 成功率 
    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% 成功率 
    Silence locally with `PYTHONWARNINGS=ignore::DeprecationWarning` for CI noise only (does NOT fix the underlying issue).

无效尝试

常见但无效的做法:

  1. 85% 失败

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

  2. 60% 失败

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