pip install dependency links

Question

I am using python version 2.7 and pip version is 1.5.6.

I want to install extra libraries from url like a git repo on setup.py is being installed.

I was putting extras in install_requires parameter in setup.py. This means, my library requires extra libraries and they must also be installed.

...
install_requires=[
    "Django",
    ....
],
...

But urls like git repos are not valid string in install_requires in setup.py. Assume that, I want to install a library from github. I have searched about that issue and I found something which I can put libraries such that in dependency_links in setup.py. But that still doesn't work. Here is my dependency links definition;

dependency_links=[
    "https://github.com/.../tarball/master/#egg=1.0.0",
    "https://github.com/.../tarball/master#egg=0.9.3",
], 

The links are valid. I can download them from a internet browser with these urls. These extra libraries are still not installed with my setting up. I also tried --process-dependency-links parameter to force pip. But result is same. I take no error when pipping.

After installation, I see no library in pip freeze result in dependency_links.

How can I make them to be downloaded with my setup.py installation?

Edited:

Here is my complete setup.py

from setuptools import setup

try:
    long_description = open('README.md').read()
except IOError:
    long_description = ''

setup(
    name='esef-sso',
    version='1.0.0.0',
    description='',
    url='https://github.com/egemsoft/esef-sso.git',
    keywords=["django", "egemsoft", "sso", "esefsso"],
    install_requires=[
        "Django",
        "webservices",
        "requests",
        "esef-auth==1.0.0.0",
        "django-simple-sso==0.9.3"
    ],
    dependency_links=[
        "https://github.com/egemsoft/esef-auth/tarball/master/#egg=1.0.0.0",
        "https://github.com/egemsoft/django-simple-sso/tarball/master#egg=0.9.3",
    ],

    packages=[
        'esef_sso_client',
        'esef_sso_client.models',
        'esef_sso_server',
        'esef_sso_server.models',
    ],
    include_package_data=True,
    zip_safe=False,
    platforms=['any'],
)

It seems, it does not use the sources in dependency_links.

Answer 1

The --process-dependency-links option to enable dependency_links was removed in Pip 19.0.

Instead, you can use a PEP 508 URL to specify your dependency, which is supported since Pip 18.1. Here's an example excerpt from setup.py:

install_requires=[
    "numpy",
    "package1 @ git+https://github.com/user1/package1",
    "package2 @ git+https://github.com/user2/package2@branch1",
],

Note that Pip does not support installing packages with such dependencies from PyPI and in the future you will not be able to upload them to PyPI (see news entry for Pip 18.1).
