根因分析

存在 pyproject.toml 但缺少 [build-system] 部分，因此 pip 无法确定构建后端。这通常发生在工具写入不完整的 pyproject.toml 时。

English

A pyproject.toml exists but lacks a [build-system] section, so pip cannot determine the build backend. This often happens when a tool writes a partial pyproject.toml.

generic

解决方案

  1. 90% 成功率 
    [build-system]
requires = ["setuptools>=61", "wheel"]
build-backend = "setuptools.build_meta"
  2. 75% 成功率 
    pip install build
python -m build --sdist  # validates pyproject.toml

无效尝试

常见但无效的做法:

  1. 85% 失败

    Disabling isolation doesn't supply the missing build-system table; pip still refuses to proceed.

  2. 60% 失败

    Removing the file forces legacy setup.py behavior, which may not exist for a PEP 517-only project.
