How to create a Pure-Python wheel

From the following setup.py file, I am trying to create a pure-python wheel from a project that should contain only python 2.7 code.

from setuptools import setup

setup(
    name='foo',
    version='0.0.1',
    description='',
    url='',
    install_requires=[
        'bpython',
        'Django==1.8.2',
    ],
)

However, when I run python setup.py bdist_wheel the wheel file that is generated is platform specific foo-0.0.1-cp27-none-macosx_10_9_x86_64.whl wheel file instead of the expected foo-0.0.1-cp27-none-any.whl. When I try to install this wheel on a different platform it fails saying it is not compatible with this Python.

I there something I need to change about the setup.py file or python interpreter, perhaps, that will allow this wheel to be used on any platform?

This part of the filename is controlled by the bdist_wheel option called python tag:

python2 setup.py bdist_wheel --help | grep python-tag
  --python-tag      Python implementation compatibility tag (default: 'py2')

However the default is generally 'py2' (or 'py3' for a python3 runtime), so to get a platform-specific wheel you must have something else in your configuration that is not shown in the question.

Regardless, you can specify the tag explicitly in your setup file:

from setuptools import setup

setup(
    name="foo",
    version="0.0.1",
    ...
    options={"bdist_wheel": {"python_tag": "cp27"}},
)

This configuration will create a wheel named foo-0.0.1-cp27-none-any.whl.

Adding the classifiers field to my setup.py fixed this issue.

from setuptools import setup

setup(
    name='foo',
    version='0.0.1',
    description='',
    url='',
    classifiers=[
        'Programming Language :: Python :: 2.7',
    ],
    install_requires=[
        'bpython',
        'Django==1.8.2',
    ],
)

The simplistic way is to add --universal to your commandline, as you can see from running python setup.py bdist_wheel --help:

  --universal       make a universal wheel (default: false)

Alternatively you can add a setup.cfg file next to your setup.py that takes care of this:

[bdist_wheel]
universal = 1

If you don't like yet another configuration file clobbering your package, you can just write such a file in your setup.py just before it calls setup() and then remove it after that call returns, this is what I do in the shared setup.py for all my projects on PyPI e.g. used in ruamel.yaml.
