package dir的结构是这个

repodir/
-------- setup.py
-------- MANIFEST.in

-------- bin/
----------- awsm.sh

-------- sound/
------------ init.py

------------ echo/
----------------- init.py
----------------- module1.py
----------------- module2.py

------------ effects/
------------------- init.py
------------------- module3.py
------------------- module4.py

setup.py

from setuptools import setup
setup(
        name = 'sound',
        version = '0.1',
        author = 'awesomeo',
        author_email = 'awesomeo@email.com',
        description = 'awesomeo',
        license = 'Proprietary',
        packages = ['sound'],
        scripts = ['bin/awsm.sh'],
        install_requires = ['Django==1.8.2', 'billiard', 'kombu', 'celery', 'django-celery' ],
        zip_safe = False,
    )

当我执行python setup.py安装时，仅将sound / init .py复制到/Library/Python/2.7/site-
packages/sound/目录。

其余子包的回声，环绕声和效果完全不被复制。Setuptools创建一个包含SOURCES.txt文件的sound.egg-info

SOURCES.txt

MANIFEST.in
setup.py
bin/awsm.sh
sound/__init__.py
sound.egg-info/PKG-INFO
sound.egg-info/SOURCES.txt
sound.egg-info/dependency_links.txt
sound.egg-info/not-zip-safe
sound.egg-info/requires.txt
sound.egg-info/top_level.txt

看起来安装程序在SOURCES.txt文件中不包含要在安装时复制的子包，这就是问题所在。

知道为什么会发生这种情况吗？
