To upgrade django-oppia, we recommend that you first uninstall the old version (pip uninstall django-oppia) and then install the new version (pip install django-oppia).
If you try to upgrade (pip install --upgrade django-oppia) , it may also reinstall TastyPie and you’ll need to reapply the timezone fix.
Once you have reinstalled OppiaMobile, run python manage.py migrate oppia and python manage.py migrate oppia.quiz to apply any database updates
Run python manage.py collectstatic this will copy all the required javascript, images, css and other static files are copied to your STATIC_ROOT
