pip ignores dependency_links in setup.py

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?

Solution

  • 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.
