No module named query on haystack

Question

I was using haystack on my Windows computer, but I realized I needed other modules for my django app that are easier to install on Linux, so I moved to my VirtualBox with Ubuntu. I installed everything with virtualenv in a venv folder. Basically my app uses haystack with a Whoosh backend. On view.py, on the import lines, when I do from haystack.query import SearchQuerySet it throws a No module named query error. Any ideas what might be wrong? Here is the entire error. I suspect I'm doing something wrong with the Python path. I installed everything with pip on the virtual env.

Answer 1

So I did a very dumb mistake. I used pip install haystack instead of pip install django-haystack.
