pythonbrew: Get up & running

pythonbrew-upNrunning

pythonbrew is a program to automate the building and installation of Python in the users $HOME. 
This is a clean way to install/manage multiple versions of python.

1. curl -kL http://xrl.us/pythonbrewinstall | bash

2. add to the end of your ~/.bashrc:
[[ -s $HOME/.pythonbrew/etc/bashrc ]] && source $HOME/.pythonbrew/etc/bashrc

3. pythonbrew install 2.7.2, pythonbrew install 3.2

4. for other useful commands, type pythonbrew help <command>

5. Create isolated python environments (uses virtualenv):

pythonbrew venv init
pythonbrew venv create proj
pythonbrew venv list
pythonbrew venv use proj (pythonbrew venv use socialwebhack, mongoDb_GNSS_trackingApp)
pythonbrew venv delete proj
pythonbrew venv rename proj proj2

OR
# .profile on OSX or .bashrc
virtualenv + virtualenvwrapper
source /usr/local/bin/virtualenvwrapper/sh
mkvirtualenv name
workon name
pip install Django

# Dump it to a requirements file in the project folder
pip freeze -l > requirements.txt

# Install packages from requirements file 
pip install -r requirements.txt
