I had a problem when I installed like below.
pip install -r requirements.txt-> Failed building wheel for Pillow
pip install -r requirements.txt
so, I first installed Pillow.and I did pip install -r ... like above.and I did it successfully!
pip install -r ...
Why has it been working like above? Anyone knows that?
Spirit does not support python 3.5 since Django did not had support for it a week ago. My guess is the required Pillow version does not support python 3.5 either.
Spirit will add support in the next release
I just tested it, it seems that dependency is all that needed to be updated.
I really thank you for answering me.
