EnvironmentError: Pillow is not compiled with JPEG support, see 'Libraries installation issues' documentation section.

Answer 1

Add JPEG support to Pillow, in Ubuntu you can do the following:

sudo apt-get install libjpeg-dev libfreetype6-dev zlib1g-dev

# Link the libraries for Pillow to find them:

sudo ln -s /usr/lib/`uname -i`-linux-gnu/libfreetype.so /usr/lib/
sudo ln -s /usr/lib/`uname -i`-linux-gnu/libjpeg.so /usr/lib/
sudo ln -s /usr/lib/`uname -i`-linux-gnu/libz.so /usr/lib/

# reinstall Pillow (In case you have Pillow already installed)
pip install --upgrade --force-reinstall pillow
