Configuring virtualenv and appengine

Google's AppEngine requires a Python 2.5 environment. I created this by first installing Python 2.5 on my system, then installing virtualenv:-

$ cd /usr/local/src
$ sudo tar -zxf virtualenv-1.5.1.tar.gz
$ cd virtualenv-1.5.1
$ sudo python setup.py install

Install AppEngine into your project folder:-

$ cd ~/appengineproject
$ unzip google_appengine_1.4.1.zip
$ sudo ln -s ~/appengineproject/google_appengine/ /usr/local/google_appengine

And finally create a virtualenv for AppEngine

$ virtualenv --python=python2.5 pythonenv

and configure it by adding the following lines to pythonenv/lib/python2.5/site-packages/gae.pth:

~/appengineproject/google_appengine
~/appengineproject/google_appengine/lib/yaml/lib
~/appengineproject/google_appengine/lib/antlr
~/appengineproject/google_appengine/lib/ipaddr
~/appengineproject/google_appengine/lib/webob
~/appengineproject/google_appengine/lib/django
~/appengineproject/google_appengine/lib/fancy_urllib
~/appengineproject/google_appengine/lib/simplejson
~/appengineproject/google_appengine/lib/graphy
