How can I make setuptools install a package from another source that's also available on pypi with the same version number?

I ended up doing something very similar to the answer in stackoverflow.com/a/17442663/368102.

I need a requests-file github package that name-conflicts with a different requests-file package in PyPi. They both have a version 1.0, and the PyPi version has some higher versions.

The workaround in my ias_tools/setup.py looks like this:

setup(
    ...
    install_requires=[
        'requests-file<=99.99',
    ],
    dependency_links=[
        'https://github.com/jvantuyl/requests-file/archive/b0a7b34af6e287e07a96bc7e89bac3bc855323ae.zip#egg=requests-file-99.99'
    ]
)

In my case, I'm using pip so I also had to use --process-dependency-links:

% pip install --process-dependency-links ./ias_tools
You are using pip version 6.0.6, however version 6.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

I'm not too worried about the deprecation notice, as a pull request was submitted to pip to deprecate the deprecation (after a discussion about it).
