pip ignores dependency_links in setup.py

Question

I have dependency_links in my setup.py:

... dependency_links = ['http://github.com/robot-republic/python-s3/tarball/master.tar.gz#egg=python-s3'], ... 

But it doesn't work. However install_requires works fine. Maybe there are another method to set up git repo as required for setup.py?

Answer 1

This answer should help. In a nutshell, you need to specify the version (or "dev") for the #egg=python-s3 so it looks like #egg=python-s3-1.0.0.

Updates based on @Cerin's comment:

• Pip 1.5.x has a flag to enable dependency-links processing: --process-dependency-links. I haven't tested it because I agree with the point below.
• This discussion seems to indicate that using dependency-links for pip is a bad practice. Although this feature was enlisted for deprecation, it's not anymore. There's a valid use case for private packages.

Answer 2

since pip version 18.1 PEP 508 URL is supported. That means you don't need the deprecated dependency_links anymore. You write the dependency directly in the install_requires list instead. The example from @Chad looks like this:

setup(     name='yourpackage',     version='1.7.5',     packages=[],     url='',     license='',     author='',     author_email='',     description='',     install_requires=[         'somepackage==1.2.0',         'repo @ https://github.com/user/archive/master.zip#egg=repo-1.0.0',         'anotherpackage==4.2.1'     ], ) 

To install your package you can simply write:

pip install yourpackage 

(without --process-dependency-links)
