virtualenv

Using virtualenv allows multiple Python applications to each have an independent set of Libraries to allow easier management of dependencies.

Install Python virtualenv

On linux install the virtualenv package using your package manager.

Ubuntu/debian:

aptitude install python-virtualenv

Windows:

1. Install setup tools from ​http://pypi.python.org/pypi/setuptools
2. Use easy_install to install virtualenv

   easy_install virtualenv
   

Using virtualenv

1. Create a new virtualenv for your application

virtualenv dependencydirectory

The above creates a directory called dependencydirectory and initializes a new virtualenv inside it.

2. Activate the virtualenv

On Linux/MacOSX/*ix:

source dependencydirectory/bin/activate

On Windows:

TODO

Note: Steps 4 works only after step 2 has been executed in the current terminal.

3. Download the required web2py version and place eden in the applications directory.

4. Use the requirements.txt in the eden directory to install the dependencies

pip install -U -r requirements.txt

5. Run web2py for development within this environment.

python web2py.py 

Using a virtualenv with apache/mod_wsgi

Append the following to WSGIDaemonProcess in the config:

 python-path=/home/web2py/dependencydirectory/lib/python2.6/site-packages

You can find further configuration details here -> ​http://code.google.com/p/modwsgi/wiki/VirtualEnvironments

Note: In the line above change python2.6 to your python version and the directory to match your directory

Using a virtualenv with uwsgi

Add -H path_to_dependencydirectory to your uwsgi parameters
