根因分析

部分安装或降级后的 setuptools 缺少内置的 _distutils 子模块，通常发生在升级失败或 distutils 导入冲突之后。

English

A partially-installed or downgraded setuptools leaves the vendored _distutils submodule missing, often after a failed upgrade or a conflicting distutils import.

解决方案

  1. 95% 成功率 
    pip uninstall -y setuptools
pip install --no-cache-dir 'setuptools>=68'
python -c "from setuptools._distutils.command.build_ext import build_ext; print('ok')"
  2. 90% 成功率 
    python -m venv .venv && source .venv/bin/activate
pip install --upgrade pip setuptools wheel
pip install .

无效尝试

常见但无效的做法:

  1. 95% 失败

    No such package on PyPI; pip returns 'No matching distribution found'.

  2. 70% 失败

    --no-deps can leave an inconsistent setuptools install if any dependency was previously removed.
