Virtual environments are isolated Python environments. They allow freedom to install specific versions of dependencies without affecting the global site-packages. They also make it easy to throw away a 'broken' environment and start again. If you need further information regarding virtual environments, please see the virtualenvwrapper documentation.

Install virtualenvwrapper

  1. Install virtualenvwrapper:
    2. sudo pip install virtualenvwrapper
  2. Add the following to your ~/.bash_profile:
    3. export WORKON_HOME=$HOME/.virtualenvs source /usr/local/bin/virtualenvwrapper.sh

Create a virtual environment for WebQA

   mkvirtualenv webqa

Switch to the WebQA virtual environment

   workon webqa

Installation on Windows

  1. Install the 32-bit version of SetupTools using the provided .exe installer.
  2. Download the last pip version from here and uncompress it.
  3. In your cmd prompt, go to the uncompressed pip directory and run python setup.py install
  4. Add C:\Python26\Scripts to your System Variables path.
  5. Now you can use the command pip install package on Win.
