make distutils in Python automatically find packages
提问by
When describing a python package in setup.pyin distutilsin Python, is there a way to make it so automatically get every directory that has a __init__.pyin it and include that as a subpackage?
当描述一个Python包setup.py在distutilsPython中，是有办法使它所以自动获得每一个有一个目录__init__.py中，并包含一个子包？
ie if the structure is:
即如果结构是：
mypackage/__init__.py
mypackage/a/__init__.py
mypackage/b/__init__.py
I want to avoid doing:
我想避免这样做：
packages = ['mypackage', 'mypackage.a', 'mypackage.b']
and instead just do:
而只是这样做：
packages = ['mypackage']
and have it automatically find things like aand bsince they have an init file. thanks.
并让它自动查找类似的东西a，b因为它们有一个 init 文件。谢谢。

The easiest way (that I know of) is to use pkgutil.walk_packagesto yield the packages:
最简单的方法（我知道的）是pkgutil.walk_packages用来产生包：
from distutils.core import setup
from pkgutil import walk_packages
import mypackage
def find_packages(path=__path__, prefix=""):
yield prefix
prefix = prefix + "."
for _, name, ispkg in walk_packages(path, prefix):
if ispkg:
yield name
setup(
# ... snip ...
packages = list(find_packages(mypackage.__path__, mypackage.__name__)),
# ... snip ...
)

I would recommend using the find_packages() function available with setuptoolssuch as:
我会建议使用find_packages（）函数可用setuptools的，例如：
from setuptools import setup, find_packages
and then do
然后做
packages=find_packages()

import re, os
def find_packages(path='.'):
ret = []
for root, dirs, files in os.walk(path):
if '__init__.py' in files:
ret.append(re.sub('^[^A-z0-9_]+', '', root.replace('/', '.')))
return ret
setup(
...
packages = find_packages()
...
)

Same as dm76 answer, just that I also have tests in my repo, so I use:
与 dm76 答案相同，只是我的 repo 中也有测试，所以我使用：
from setuptools import find_packages
packages=find_packages(exclude=["*.tests", "*.tests.*", "tests.*", "tests"]),
