  <p>It does, however work when I try installing on a venv.</p>
  
  <p>Could this have anything to do with $PYTHONPATH?</p>
  
  <p>(I believe this is also causing conflicts when I try to run runserver on an already started project. But I will leave that for another question if this one doesn't resolve it.)</p>
