python - setuptools中的package_data有什么用？

Question

我试图通过引用这个网站来了解它的用途以及为什么我们应该使用它:

https://python-packaging.readthedocs.io/en/latest/non-code-files.html

但是我还是没能理解。谁能给我展示更多示例或使用方法。

您指向的文档已过时且相当简洁。最好读一下:https://setuptools.readthedocs.io/en/latest/setuptools.html#including-data-files

The package_data argument is a dictionary that maps from package names to lists of glob patterns.

示例:

from setuptools import setup
setup(
    ...
    package_data={
        # If any package contains *.txt or *.rst files, include them:
        '': ['*.txt', '*.rst'],
        # And include any *.msg files found in the 'hello' package, too:
        'hello': ['*.msg'],
    }
)
