根因分析

setuptools 移除了 2to3 构建选项（2018 年起弃用，setuptools 58 移除）。向 setup() 传入 use_2to3=True 的旧 setup.py 现在会失败。

English

setuptools removed the 2to3 build option (deprecated since 2018, removed in setuptools 58). Old setup.py files passing use_2to3=True to setup() now fail.

解决方案

  1. 80% 成功率 
    pip install 'setuptools<58' wheel
pip install <old-package> --no-build-isolation
  2. 70% 成功率 
    # edit setup.py: remove use_2to3=True
# then
pip install . --no-build-isolation
  3. 65% 成功率 
    pip index versions <alternative-package>
pip install <maintained-fork>

无效尝试

常见但无效的做法:

  1. 90% 失败

    Latest setuptools still has no 2to3 support.

  2. 85% 失败

    The option was removed from setuptools, not just pip.

  3. 60% 失败

    Sometimes there is no newer release; the package is abandoned.
