步骤1:创建MANIFEST。和setup.py在同一个文件夹里

步骤2:在MANIFEST.in中包含要添加的文件的相对路径

include README.rst
include docs/*.txt
include funniest/data.json

步骤3:在setup()函数中设置include_package_data=True，将这些文件复制到site-package

对于要包含在安装中的非python文件，它们必须位于已安装包目录中的一个目录中。如果您在MANIFEST中指定包目录之外的非python文件。中，它们将包含在您的发行版中，但不会被安装。在包目录之外安装任意文件的“文档化”方式并不可靠(现在每个人都注意到了)。

The above answer from Julian Mann copies the files to your package directory in the build directory, so it does work, but not if you are installing in editable/develop mode (pip install -e or python setup.py develop). Based on this answer to a related question (and Julian's answer), below is an example that copies files to your installed package location either way after all the other install/develop tasks are done. The assumption here is that files file1 and file2 in your root-level data directory will be copied to your installed package directory (my_package), and that they will be accessible from python modules in your package using os.path.join(os.path.dirname(__file__), 'file1'), etc.

记得也要做清单。在上面描述的东西中，以便这些文件也包含在您的发行版中。为什么setuptools会在你的发行版中包含文件，然后默默地不安装它们，这超出了我的理解范围。尽管在包目录之外安装它们可能更可疑。

import os
from setuptools import setup
from setuptools.command.develop import develop
from setuptools.command.install import install
from shutil import copyfile

HERE = os.path.abspath(os.path.dirname(__file__))
NAME = 'my_package'

def copy_files (target_path):
    source_path = os.path.join(HERE, 'data')
    for fn in ["file1", "file2"]:
        copyfile(os.path.join(source_path, fn), os.path.join(target_path,fn))

class PostDevelopCommand(develop):
    """Post-installation for development mode."""
    def run(self):
        develop.run(self)
        copy_files (os.path.abspath(NAME))

class PostInstallCommand(install):
    """Post-installation for installation mode."""
    def run(self):
        install.run(self)
        copy_files (os.path.abspath(os.path.join(self.install_lib, NAME)))

setup(
    name=NAME,
    cmdclass={
        'develop': PostDevelopCommand,
        'install': PostInstallCommand,
    },
    version='0.1.0',
    packages=[NAME],
    include_package_data=True,
    setup_requires=['setuptools_scm'],
)

我找到了一个解决办法:我将我的lgpl2.1 .1_license.txt重命名为lgpl2.1 .1_license.txt.py，并在文本周围加上一些三引号。现在我不需要使用data_files选项，也不需要指定任何绝对路径。我知道把它变成Python模块很难看，但我认为它没有指定绝对路径难看。

这里有一个对我有用的更简单的答案。

首先，根据上面Python Dev的注释，setuptools是不需要的:

package_data is also available to pure distutils setup scripts 
since 2.3. – Éric Araujo

这很好，因为在包中添加setuptools要求意味着您也必须安装它。简而言之:

from distutils.core import setup

setup(
    # ...snip...
    packages          = ['pkgname'],
    package_data      = {'pkgname': ['license.txt']},
)

在setup.py下的setup(:

setup(
   name = 'foo library'
   ...
  package_data={
   'foolibrary.folderA': ['*'],     # All files from folder A
   'foolibrary.folderB': ['*.txt']  #All text files from folder B
   },

创建清单。在项目根用递归include到所需目录或用文件名include。

include LICENSE
include README.rst
recursive-include package/static *
recursive-include package/templates *
