pythonz: a Python installation manager


pythonz is a program to automate the building and installation of Python in the users $HOME. This is a fork of the original project, pythonbrew.

The original project seems to be unmaintained, and it also has some extra features which I don't really need, so I made this for to make something a bit simpler that works for me. You may also find it useful.

CPython, Stackless, PyPy and Jython are supported.


The recommended way to download and install pythonz is to run these statements in your shell:

curl -kL | bash


fetch -o - | bash

After that, pythonz installs itself to ~/.pythonz.

Please add the following line to the end of your ~/.bashrc:

[[ -s $HOME/.pythonz/etc/bashrc ]] && source $HOME/.pythonz/etc/bashrc

If you need to install pythonz into somewhere else, you can do that by setting a PYTHONZ_ROOT environment variable:

export PYTHONZ_ROOT=/path/to/pythonz
curl -kLO
chmod +x pythonz-install

For Systemwide (Multi-User) installation

If the install script is run as root, pythonz will automatically install into /usr/local/pythonz.

pythonz will be automatically configured for every user on the system if you install it as root.

After installing it, where you would normally use sudo, non-root users will need to use sudo-pythonz:

sudo-pythonz install 2.7.3


pythonz command [options] version

Install some pythons:

pythonz install 2.7.3
pythonz install -t stackless 2.7.2
pythonz install -t jython 2.5.2
pythonz install -t pypy --url 1.8
pythonz install --verbose 2.7.2
pythonz install --configure="CC=gcc_4.1" 2.7.2
pythonz install --url 2.7.2
pythonz install --file /path/to/Python-2.7.2.tgz 2.7.2
pythonz install 2.7.3 3.2.3

List the installed pythons:

pythonz list

List all the available python versions for installing:

pythonz list -a

Uninstall the specified python:

pythonz uninstall 2.7.3
pythonz uninstall -t stackless 3.2.2

Remove stale source folders and archives:

pythonz cleanup

Upgrades pythonz to the latest version:

pythonz update

The recommended way to use a pythonz-installed version of Python is through virtualenv, e.g.:

mkvirtualenv -p ~/.pythonz/pythons/CPython-2.7.3/bin/python python2.7.3

For more information about virtualenv, checkout its documentation.
