根因分析

setuptools 58+ 移除了 2to3 构建支持。setup.py 中带有 `use_2to3=True` 的包现在会失败，因为该选项已不存在。

English

setuptools 58+ removed the 2to3 build support. Packages with `use_2to3=True` in setup.py now fail because the option no longer exists.

解决方案

  1. 80% 成功率 
    pip install 'setuptools<58' wheel
pip install --no-build-isolation <package>
  2. 75% 成功率 
    pip install --only-binary=:all: <package>

无效尝试

常见但无效的做法:

  1. 70% 失败

    Many legacy packages are unmaintained; the latest release still contains use_2to3=True.

  2. 95% 失败

    The 2to3 tool is part of the stdlib; installing a package named 2to3 does not restore setuptools' removed option.
