Does pip handle extras_requires from setuptools/distribute based sources?

Question

I have package \"A\" with a setup.py and an extras_requires line like:

extras_require = {
    \'ssh\':  [\'paramiko\'],
},

And a package \"

Answer 1

This is suppported since pip 1.1, which was released in February 2012 (one year after this question was asked).

Answer 2

We use setup.py and pip to manage development dependencies for our packages, though you need a newer version of pip (we're using 1.4.1 currently).

#!/usr/bin/env python
from setuptools import setup
from myproject import __version__ 

required = [
    'gevent',
    'flask',
    ...
]

extras = {
    'develop': [
        'Fabric',
        'nose',
    ]
}

setup(
    name="my-project",
    version=__version__,
    description="My awsome project.",
    packages=[
        "my_project"
    ],
    include_package_data=True,
    zip_safe=False,
    scripts=[
        'runmyproject',
    ],
    install_requires=required,
    extras_require=extras,
)

To install the package:

$ pip install -e . # only installs "required"

To develop:

$ pip install -e .[develop] # installs develop dependencies

Answer 3

The answer from @aaronfay is completely correct but it may be nice to point out that if you're using zsh that the install command pip install -e .[dev] needs to be replaced by pip install -e ".[dev]".
