This document will get you up and running with Django. Install Python Being a Python Web framework, Django requires Python. It works with any Python version from 2.5 to 2.7 (due to backwards incompatibilities in Python 3.0, Django does not currently work with Python 3.0; see the Django FAQ for more information on supported Python versions and the 3.0 transition). Get Python at http://www.python.org . If you’re running Linux or Mac OS X, you probably already have it installed. Django on Jython If you use Jython (a Python implementation for the Java platform), you’ll need to follow a few additional steps. See Running Django on Jython for details. Python on Windows On Windows, you might need to adjust your PATH environment variable to include paths to Python executable and additional scripts. For example, if your Python is installed in C:\Python27\ , the following paths need to be added to PATH : C:\Python27\;C:\Python27\Scripts; Install Apache and mod_ws...

Install Ruby 1.9 The best and easiest way we've found to install Ruby on Windows is using the RubyInstaller . It's a self-contained Windows installer (an .exe file) that includes a Ruby language execution environment, a baseline set of RubyGems, and documentation. Installers are available for a number of popular Ruby versions. We'll be installing Ruby 1.9.2, the latest Ruby version that's supported for use with Rails 3. On the RubyInstaller downloads page , download the file named Ruby 1.9.2-p290 . You can either download the executable installer (recommended) or the 7-zip archive . The rest of the instructions assume you downloaded the executable installer. Once the executable installer has downloaded, use Windows Explorer to navigate to where you saved the .exe file and double-click it to start the installation process. Off you go, but pay attention to the prompts... ...
