| 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 [http://www.doughellmann.com/docs/virtualenvwrapper/index.html virtualenvwrapper documentation]. | | 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. We recommend using '''virtualenvwrapper''' for managing your virtual environments. See the documentation for a guide to [http://virtualenvwrapper.readthedocs.org/en/latest/install.html installation] and the [http://virtualenvwrapper.readthedocs.org/en/latest/command_ref.html command reference]. There's also a useful introduction to virtualenv and virtualenvwrapper in [http://www.silverwareconsulting.com/index.cfm/2012/7/24/Getting-Started-with-virtualenv-and-virtualenvwrapper-in-Python this blog post]. |
