Good day

I'm working through a Django projects book called Django by example

I am stuck working through the projects because I seem to be having trouble with 3rd party packages, namely taggit and pillow

Using pillow as an example.. This is the error I get when I makemigrations for my apps model:

(shop) PS C:\dan_projects\django_by_example_shop\myshop> py -3 .\manage.py makemigrations
SystemCheckError: System check identified some issues:
ERRORS:
shop.Product.image: (fields.E210) Cannot use ImageField because Pillow is not installed.
HINT: Get Pillow at https://pypi.python.org/pypi/Pillow or run command "pip install Pillow".

Yet 'pip freeze' is telling me that pillow is installed:

(shop) PS C:\dan_projects\django_by_example_shop\myshop> pip freeze
Django==1.8.5
Pillow==2.9.0

Any help would be greatly appreciated!!
