根因分析

setup.py 声明了 packages=['mypkg'] 和 package_dir={'':'src'}，但 src/mypkg 目录缺失或命名不同。常见于搭建 src 布局项目时忘记创建包文件夹。

English

setup.py declares packages=['mypkg'] and package_dir={'':'src'} but the src/mypkg directory is missing or named differently. Common when scaffolding a src-layout project and forgetting to create the package folder.

解决方案

  1. 98% 成功率 
    mkdir -p src/mypkg && touch src/mypkg/__init__.py
  2. 95% 成功率 
    from setuptools import setup, find_packages; setup(packages=find_packages(where='src'), package_dir={'':'src'})
  3. 92% 成功率 
    [tool.setuptools.packages.find]\nwhere = ["src"]

无效尝试

常见但无效的做法:

  1. 90% 失败

    Build isolation is not the issue; the source tree is malformed.

  2. 70% 失败

    find_packages() defaults to where='.' and will not find packages under src/.
