Passing arguments in python setup.py install_requires list

Question

I have used pip to install PIL. It requires two additional arguments while installation. So the command for installation looks something like this.

pip insta         


        

Answer 1

Currently, there is no way to specify extra arguments in install_requires in setup.py. But, I solved my problem of installing dependencies with global-options by sub-classing setuptools.command.install class and overriding its run() method, like following code -

from setuptools import setup
from setuptools.command.install import install
from subprocess import call


class CustomInstall(install):
    def run(self):
        install.run(self)
        call(['pip', 'install', 'PIL', '--allow-external', 'PIL', '--allow-unverified', 'PIL'])

setup( ...
      cmdclass={
          'install': CustomInstall,
      },
)
