I faced a similar situation where I want to use shapely as one of my package dependency. Shapely, however, has a caveat that if you are using windows, you have to use the .whl file from http://www.lfd.uci.edu/~gohlke/pythonlibs/. Otherwise, you have to install a C compiler, which is something I don't want. I want the user to simply use pip install mypackage instead of installing a bunch of other stuffs.

And if you have the typical setup with dependency_links

setup(
  name = 'streettraffic',
  packages = find_packages(), # this must be the same as the name above
  version = '0.1',
  description = 'A random test lib',
  author = 'Costa Huang',
  author_email = 'Costa.Huang@outlook.com',
  install_requires=['Shapely==1.5.17'],
  dependency_links = ['http://www.lfd.uci.edu/~gohlke/pythonlibs/ru4fxw3r/Shapely-1.5.17-cp36-cp36m-win_amd64.whl']
)

and run pip install ., it is simply going to pick the shapely on Pypi and cause trouble on Windows installation. After hours of researching, I found this link Force setuptools to use dependency_links to install mysqlclient and basically use from setuptools.command.install import install as _install to manually install shapely.

from setuptools.command.install import install as _install
from setuptools import setup, find_packages
import pip

class install(_install):
  def run(self):
    _install.do_egg_install(self)

    # just go ahead and do it
    pip.main(['install', 'http://localhost:81/Shapely-1.5.17-cp36-cp36m-win_amd64.whl'])

setup(
  name = 'mypackage',
  packages = find_packages(), # this must be the same as the name above
  version = '0.1',
  description = 'A random test lib',
  author = 'Costa Huang',
  author_email = 'test@outlook.com',
  cmdclass={'install': install}
)

And the script works out nicely. Hope it helps.
