pythonz: a Python installation manager
Overview
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.
Installation
The recommended way to download and install pythonz is to run these statements in your shell:
curl -kL https://raw.github.com/saghul/pythonz/master/pythonz-install | bash
or:
fetch -o - https://raw.github.com/saghul/pythonz/master/pythonz-install | 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 https://raw.github.com/saghul/pythonz/master/pythonz-install chmod +x pythonz-install ./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
Before installing Pythons via Pythonz
You might want to install some optional dependencies, for functionality that is often expected to be included in a Python build (it can be a bummer to discover these missing and have to rebuild your python setup). These include the following, ordered by (very roughly guessed) probability that you will need them:
Debian family (Ubuntu...)
sudo apt-get install build-essential zlib1g-dev libbz2-dev libssl-dev libreadline-dev libncurses5-dev libsqlite3-dev libgdbm-dev libdb-dev libexpat-dev libpcap-dev liblzma-dev libpcre3-dev
If you need tkinter support, add tk-dev.
RPM family (CentOS, RHEL...)
yum groupinstall "Development tools" yum install zlib-devel bzip2-devel openssl-devel readline-devel ncurses-devel sqlite-devel gdbm-devel db4-devel expat-devel libpcap-devel xz-devel pcre-devel
If you need tkinter support, add tk-devel.
OSX
xcode-select --install

Recommended way to use a pythonz-installed version of Python
For Python <= 3.2
Use virtualenv, e.g.:
mkvirtualenv -p $(pythonz locate 2.7.3) python2.7.3
For more information about virtualenv, checkout its documentation.
For Python >= 3.3
Use pyvenv directly from Python, e.g.:
/usr/local/pythonz/pythons/CPython-3.4.1/bin/pyvenv pyvenv
For more information about pyvenv, checkout its documentation.
DTrace support
CPython versions 2.7.6 and 3.3.4 can be built with DTrace suport. Patches adding support for DTrace have been taken from this page by Jesús Cea.
Building Python with DTrace support:
pythonz install --configure="--with-dtrace" 2.7.6
