根因分析

在 setuptools 的自动包发现下，包含多个顶层目录（如包目录和 `tests`/`docs`）的扁平项目布局存在歧义，因此 setuptools 拒绝猜测。

English

With setuptools' automatic package discovery, a flat project layout containing more than one top-level directory (e.g. the package and a `tests`/`docs` dir) is ambiguous, so setuptools refuses to guess.

解决方案

  1. 92% 成功率 
    Declare packages explicitly in pyproject.toml: `[tool.setuptools.packages.find] include = ["foo*"] exclude = ["tests*"]`.
  2. 90% 成功率 
    Move the package into a `src/` layout and set `[tool.setuptools.packages.find] where = ["src"]`.

无效尝试

常见但无效的做法:

  1. 85% 失败

    Loses test code and does not address the discovery ambiguity.

  2. 70% 失败

    May still collide with other top-level dirs and is a cosmetic change.
