Requirements:
- pillow
- sqlalchemy
- bottle
Before installing pillow (PIL):
Make sure you have libjpeg-dev
that provides for JPEG decoding:
sudo apt install libjpeg-dev # or yum install libjpeg-devel or whatever
sudo pip3 install pillow
If you still don't have the JPEG decoder:
sudo pip3 install -I --no-cache-dir pillow
