Python live dependency installation via pip (PyPI)

Question

I want to pull the live version of a package as a dependency of another package I install with pip.

Now, I have already found out how to install a live version of a package via pip; and that is not the question I am asking here.

I'd like to know whether I can pull in a live dependency version (e.g. from the PyPI index) - at present I was only able to set up tarballs via PyPI.

Answer 1

In your setup.py, do:

from setuptools import setup


setup(
    ...
    install_requires=[
        'a_required_pypi_package',
        'another_package_in_pypi>=minimum_version'
    ]
    ...
)

and pip, setup.py install or setup.py develop will take care of it.

However the requirement will be considered satisfied, if any version of a_required_pypi_package is installed. This is especially true, if you use pip freeze to write a requirements.txt and use it to install packages.
