How can I make setuptools install a package that's not on PyPI?

I've just started working with setuptools and virtualenv. My package requires the latest python-gearman that is only available from GitHub. The python-gearman version that's on PyPI is an old one. The Github source is setuptools-compatible, i.e. has setup.py, etc. Is there a way to make setuptools download and install the new version instead of looking for it on PyPI and installing the old one?

FYI, the new python-gearman is http://github.com/mtai/python-gearman

pypi distutils setuptools python

As I just had to do the same thing, I found another way to do this as pip's --process-dependency-links are scheduled to be removed in pip 19.0 according to this comment.

pip 18.1 includes the following feature

Allow PEP 508 URL requirements to be used as dependencies.

From the description of PEP 508, the syntax for such URL dependencies looks like:

A minimal URL based lookup:

pip @ https://github.com/pypa/pip/archive/1.3.1.zip#sha1=da9234ee9982d4bbb3c72346a6de940a148ea686

So in your setup.py it would look like

setup(
   ...
   install_requires = [
   ...
   'python-gearman @ https://github.com/mtai/python-gearman/archive/master.zip'
   ...
   ]
)

Notice, the link is an archive file and could also be a specific release or branch of a repository as described in this answer. Also, see that answer for working with other repository hosts.

To the best of my knowledge, the easiest way to update the dependency is by using pip install -I . when installing your package from its directory.
