根因分析

项目没有 setup.py（仅 pyproject.toml），但某个工具或 pip 调用假定使用旧的 setup.py 入口，或工作目录错误。

English

The project has no setup.py (pyproject.toml-only) but a tool or pip invocation assumes the legacy setup.py entry point, or the working directory is wrong.

generic

解决方案

  1. 92% 成功率 
    Add a minimal pyproject.toml with a build backend:
[build-system]
requires = ["setuptools>=61"]
build-backend = "setuptools.build_meta"

[project]
name = "foo"
version = "1.0.0"
  2. 85% 成功率 
    Confirm you are in the project root:
ls pyproject.toml setup.py setup.cfg
pip install .

无效尝试

常见但无效的做法:

  1. 85% 失败

    An empty setup.py makes the build fail later with 'no commands supplied' or metadata errors.

  2. 70% 失败

    Still expects a build backend; if pyproject.toml is missing, there is nothing to build.
