Python
Enables local Python and local Python package installation.
Local Python Installation
pythonz builds and installs multiple Python versions locally in the home directory.
This module prepends the pythonz directory to the path variable to enable the
execution of pythonz
.
Usage
Install Python versions with pythonz install
into ~/.pythonz/pythons.
Local Package Installation
Since version 2.6, Python supports per user package installation, as defined in PEP 370.
This module prepends per user site directories to the relevant path variables to enable the execution of user installed scripts and the reading of documentation.
Usage
Install packages into the per user site directory with easy_install --user
or
pip install --user
.
virtualenvwrapper
virtualenvwrapper is a frontend to the popular virtualenv utility.
virtualenv creates isolated Python environments and virtualenvwrapper provides convenient shell functions to create, switch, and manage them.
Usage
Install virtualenvwrapper.
Virtual environments are stored in ~/.virtualenvs.
There are configuration variables that have to be set to enable certain features. If you wish to use these features, export the variables in ~/.zshenv
The variable $PROJECT_HOME
tells virtualenvwrapper where to place project
working directories. It must be set and the directory created before mkproject
is used. Replace Developer with your projects directory.
export PROJECT_HOME="$HOME/Developer"
The variable $VIRTUALENVWRAPPER_VIRTUALENV_ARGS
tells virtualenvwrapper what
arguments to pass to virtualenv
. For example, set the value to
--no-site-packages to ensure that all new environments are isolated from the
system site-packages directory.
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages'

Theming
To display the name of the current virtual enviroment in a prompt, define the
following style in the prompt_theme_setup
function.
# %v - virtualenv name.
zstyle ':prezto:module:python:info:virtualenv' format 'virtualenv:%v'
Then add $python_info[virtualenv]
to $PROMPT
or $RPROMPT
and call
python-info
in the prompt_theme_preexec
hook function.
