根因分析

setuptools 找不到 setup.py 中 packages 或 package_dir 参数指定的包目录。这发生在目录名拼写错误或包结构不正确时。

English

setuptools cannot find the package directory specified in setup.py's packages or package_dir argument. This happens when the directory name is misspelled or the package structure is incorrect.

解决方案

  1. 95% 成功率 
    Verify the package directory exists and matches the name in setup.py. Use find_packages() to automatically discover packages.
  2. 90% 成功率 
    If using src layout, specify package_dir={'': 'src'} and ensure the directory structure is correct.

无效尝试

常见但无效的做法:

  1. 80% 失败

    The package won't contain the intended modules, leading to import errors at runtime.

  2. 75% 失败

    setuptools may not include any packages, resulting in an empty distribution.
