How to include license file in setup.py script?

问题

I have written a Python extension module in C++. I plan to distribute the module with setuptools. There will be binary distributions for 32- and 64-bit Windows (built with setup.py bdist_egg) and a source distribution for UNIX-like platforms (built with setup.py sdist).

I plan to license the module under the BSD license. In my source tree, the file LICENSE.txt is in the top folder along with setup.py. How should I include it in the installation package?

I tried the following setup.py script:

from setuptools import setup, Extension
from glob import glob

setup(
    name = 'Foo',
    version = '0.1.0',
    ext_modules = [Extension('Foo', glob('Source/*.cpp'))],
    package_data = {'': ['LICENSE.txt']}
)

It did not work, the license file is not included in the installation package. Maybe because the setup.py file does not define any packages, only a single extension module.

How do I fix this?

回答1:

Write a setup.cfg file and in there specify:

[metadata]
license_files = LICENSE.txt

For this to work it seems like wheel is required to be installed. That is:

pip install wheel

If you have wheel already installed and it doesn't work, try to update it:

pip install --upgrade wheel

Then when installing the package via pip install <path> the LICENSE file gets included.

回答2:

Using a METADATA.in file, the license can be included both the source package and wheels automatically:

METADATA.in include README.md include COPYING

New setuptools (40.x) allows metadata, including license, to be stored in the setup.cfg's "metadata" section. If you use older setuptools you could provide license using the "license" named argument in your setup():

def read_text(file_name: str):
    return open(os.path.join(base_path, file_name)).read()


setup(
    name = 'Foo',
    version = '0.1.0',
    ext_modules = [Extension('Foo', glob('Source/*.cpp'))],
    # package_data = {'': ['LICENSE.txt']}
    license=read_text("LICENSE.txt")
)

You have to move the LICENSE.txt file into the package directory for your project. It cannot reside the top level. Python directories get deployed, not the deployment artifact. If you create a python package, that package actually contains a number of subpackages. Each subpackage must contain ALL the files relevant to deployment.

Do not use data_files as it will actually distribute the files as a separate package. (I've heard package_files works, but I have yet to see a working example to do this).

For example:

setup(
    ...
    license="ZPL",
    classifiers=[
        ...
        'License :: OSI Approved :: Zope Public License',
        ...
        ],
     ...)

additionally you can insert your licence text into 'long_description':

setup(
    ...
    long_description="Package description. \nLicense Text",
    ...)
