使用 pip 安装包不会创建我的所有文件

Question

Stackness 交换的各位居民，您好，

我有一个要分发的库。我创建了一个 setup.py 并运行

python setup.py sdist

我看到它在 dist/ 目录下创建了一个 .tar.gz 文件，其中包含我想要的所有文件和文件夹。但是，当我将它安装在 Windows 8 机器上（运行 Python 3.6.5rc1）时，我没有得到任何文件——只有一个 kivydnd-0.5.dist-info 目录。当我在 Linux 上安装它（运行 Fedora 26、Python 2.7）时，我确实看到了包的文件，但我没有看到示例目录。

你能告诉我我做错了什么吗？

setup.py 在这里：

from setuptools import setup, find_packages

setup(
    name='kivydnd',
    version='0.5',
    description='Kivy Drag-n-Drop for Widgets',
    url='https://github.com/GreyGnome/KivyDnD',
    author='GreyGnome',
    author_email='myemail@example.com',
    license='Apache License 2.0',
    #packages=find_packages('kivydnd'),
    packages=['kivydnd'],
    zip_safe=False,
    scripts=[
        'examples/dndexample1.py',
        'examples/dndexample2.py',
        'examples/dndexample3.py',
        'examples/dndexample_copy_draggable.py',
        'examples/dndexample_drop_groups.py',
        'examples/dndexample_relative_layout.py',
        'examples/example_base_classes.py',
        'examples/example_base_classes.pyc',
        ]
)

在我的开发目录中，我执行：

    python setup.py sdist

生成的 .tar.gz 看起来像这样；这也将反映我正在开发的目录的结构：

我的 setup.py 看起来应该是这样的。该包将安装在 Python 的 site-packages 目录下，示例在 <path-to-share>/kivydnd-examples 下。

from setuptools import setup, find_packages
from codecs import open
from os import path

with open(path.join('.', 'README.md'), encoding='utf-8') as f:
    long_description = f.read()

setup(
    name='kivydnd',
    version='0.5.0',
    description='Kivy Drag-n-Drop for Widgets',
    long_description=long_description,
    long_description_content_type='text/markdown',
    url='https://github.com/GreyGnome/KivyDnD',
    author='GreyGnome',
    author_email='myemail@example.com',
    license='Apache License 2.0',
    keywords='kivy drag-n-drop',
    packages=find_packages(exclude=[]),
    data_files=[('share/kivydnd-examples',
        [
            'examples/dndexample1.py',
            'examples/dndexample2.py',
            'examples/dndexample3.py',
            'examples/dndexample_copy_draggable.py',
            'examples/dndexample_drop_groups.py',
            'examples/dndexample_relative_layout.py',
            'examples/example_base_classes.py',
            'examples/example_base_classes.pyc',
        ]
    )],
)
