Root Cause

MANIFEST.in did not include the data file in the sdist, so the installed package is missing it. The error surfaces at runtime when the code tries to open the file.

generic

中文

MANIFEST.in 未将数据文件包含在 sdist 中，因此安装的包缺少该文件。错误在运行时尝试打开文件时出现。

Workarounds

  1. 95% success 
    echo 'recursive-include mypkg/data *.yaml' >> MANIFEST.in
  2. 97% success 
    [tool.setuptools.package-data]\nmypkg = ["data/*.yaml"]
  3. 90% success 
    python -m build --sdist && tar -tzf dist/*.tar.gz | grep config.yaml

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Reinstalling the same incomplete sdist produces the same result.

  2. 60% fail

    Not reproducible; breaks on the next install.
