If you're familiar with Python packaging and installation, and just want to know what tools are currently recommended, then here it is.

Installation Tool Recommendations

Packaging Tool Recommendations


[1]There are some cases where you might choose to use easy_install (from :ref:`setuptools`), e.g. if you need to install from :term:`Eggs <Egg>` (which pip doesn't support). For a detailed breakdown, see :ref:`pip vs easy_install`.
[2]The acceptance of PEP 453 means that :ref:`pip` will be available by default in most installations of Python 3.4 or later. See the :pep:`rationale section <453#rationale>` from PEP 453 as for why pip was chosen.
[3]:ref:`get-pip.py <pip:get-pip>` and :ref:`virtualenv` install :ref:`wheel`, whereas :ref:`ensurepip` and :ref:`venv <venv>` do not currently. Also, the common "python-pip" package that's found in various linux distros, does not depend on "python-wheel" currently.
[4]Beginning with Python 3.4, venv will create virtualenv environments with pip installed, thereby making it an equal alternative to :ref:`virtualenv`. However, using :ref:`virtualenv` will still be recommended for users that need cross-version consistency.
[5]

Although you can use pure distutils for many projects, it does not support defining dependencies on other projects and is missing several convenience utilities for automatically populating distribution metadata correctly that are provided by setuptools. Being outside the standard library, setuptools also offers a more consistent feature set across different versions of Python, and (unlike distutils), setuptools will be updated to produce the upcoming "Metadata 2.0" standard formats on all supported versions.

Even for projects that do choose to use distutils, when :ref:`pip` installs such projects directly from source (rather than installing from a prebuilt :term:`wheel <Wheel>` file), it will actually build your project using :ref:`setuptools` instead.

[6]distribute (a fork of setuptools) was merged back into :ref:`setuptools` in June 2013, thereby making setuptools the default choice for packaging.
[7]:term:`PyPI <Python Package Index (PyPI)>` currently only allows uploading Windows and Mac OS X wheels, and they should be compatible with the binary installers provided for download from python.org. Enhancements will have to be made to the :pep:`wheel compatibility tagging scheme <425>` before linux wheels will be allowed.
