Success!!
To start using Django you will need
to activate the local Python and Ruby
environment:
$ source $RUBY_DIR/scripts/rvm
$ source $PYTHON_DIR/bin/activate
To initialize and start a local instance of Django:
$ cd $BASE/mitx
$ django-admin.py syncdb --settings=envs.dev --pythonpath=.
$ django-admin.py migrate --settings=envs.dev --pythonpath=.
$ django-admin.py runserver --settings=envs.dev --pythonpath=.

This document describes how to set up the MITx development environment
for both Linux (Ubuntu) and MacOS (OSX Lion).
There is also a script "create-dev-env.sh" that automates these steps.
1) Make an mitx_all directory and clone the repos
(download and install git and mercurial if you don't have them already)
mkdir ~/mitx_all
cd ~/mitx_all
git clone git@github.com:MITx/mitx.git
git clone git@github.com:MITx/askbot-devel
hg clone ssh://hg-content@gp.mitx.mit.edu/data
2) Install OSX dependencies (Mac users only)
a) Install the brew utility if necessary
/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"
b) Install the brew package list
cat ~/mitx_all/mitx/brew-formulas.txt | xargs brew install
c) Install python pip if necessary
sudo easy_install pip
d) Install python virtualenv if necessary
sudo pip install virtualenv virtualenvwrapper
e) Install coffee script
curl http://npmjs.org/install.sh | sh
npm install -g coffee-script
3) Install Ubuntu dependencies (Linux users only)
sudo apt-get install curl python-virtualenv build-essential python-dev gfortran liblapack-dev libfreetype6-dev libpng12-dev libxml2-dev libxslt-dev yui-compressor coffeescript
4) Install rvm, ruby, and libraries
echo "export rvm_path=$HOME/mitx_all/ruby" > $HOME/.rvmrc
curl -sL get.rvm.io | bash -s stable
source ~/mitx_all/ruby/scripts/rvm
rvm install 1.9.3
gem install bundler
cd ~/mitx_all/mitx
bundle install
5) Install python libraries
source ~/mitx_all/python/bin/activate
cd ~/mitx_all
pip install -r askbot-devel/askbot_requirements.txt
pip install -r askbot-devel/askbot_requirements_dev.txt
pip install -r mitx/pre-requirements.txt
pip install -r mitx/requirements.txt
6) Create log and db dirs
mkdir ~/mitx_all/log
mkdir ~/mitx_all/db
7) Start the dev server
To start using Django you will need
to activate the local Python and Ruby
environment:
$ source ~/mitx_all/ruby/scripts/rvm
$ source ~/mitx_all/python/bin/activate
To initialize and start a local instance of Django:
