If you've got an earlier version of virtualenv (IIRC, version 1.4 or earlier), this was the default option when you created a virtualenv. When you construct a virtualenv in this way, it's an extension of your system - so anything in your system PYTHONPATH will also show up in your virtualenv. If, on the other hand, you create your virtualenv with --no-site-packages (which is the default on more recent versions of virtualenv), the virtualenv is completely isolated. If you don't install a package in your virtualenv, it won't be available. To check what version of virtualenv you have, the usual --version flag works; if you run --help, the description for --no-site-packages will tell you whether it's the default or not. As for checking where a package has come from -- if you're in a Python shell, you can ask Python itself where it got a module. For example: >>> import django >>> django.__file__ '/Users/rkm/.virtualenvs/sample/lib/python2.7/site-packages/django/__init__.pyc' tells you that I'm getting Django from the version installed in my "sample" virtualenv. I hope that helps. Yours, Russ Magee %-) -- You received this message because you are subscribed to the Google Groups "Django users" group.
