- virtualenv is a tool to create isolated Python environments. The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? If you install everything into /usr/lib/python2.7/site-packages (or whatever your platform’s standard location is), it’s easy to end up in a situation where you unintentionally upgrade an application that shouldn’t be upgraded.
"Now, you’re ready to create your virtualenv. BUT FIRST…you have a decision to make. Do you want this virtualenv to use packages from your system site-packages on install them in the virtualenv’s site-packages? By default, virtualenv will symlink to your system’s site-packages if you install a package in the virtualenv that is already installed on your system. If you want a totally (well, as much as is possible) isolated virtualenv, you’ll want to do the latter. To do this, you pass in the -–no-site-packages switch when creating your virtualenv."
