Activating a virtual env not working

Question

I created two virtualenv and I installed two different versions of django. Now I have a problem to activate the two environment, I do like this :

source Django1.6/bin/activate

Then I see that the environment was activated. Then I do :

pip install django # for test

and I get this message :

Requirement already satisfied (use --upgrade to upgrade): 
                                 django in /usr/local/lib/python2.7/dist-packages

This tell that the environment was not activated but it use the default one. Why I'm getting this?

Answer 1

When changing the environment location we must execute virtualenv on the new folder. When looking to activate file I have found this code :

VIRTUAL_ENV="/old/folder"
export VIRTUAL_ENV

This variable will updated when we execute virtualenv on the new folder.
