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

Install the required libs:

http://pillow.readthedocs.org/en/latest/installation.html#linux-installation

Then uninstall and reinstall Pillow in your virtualenv

pip uninstall Pillow
pip install --no-cache-dir Pillow

I actually found the chosen solution here to be great help. I also found that the djangcms installer wants a specific version of Pillow, which results in it not picking up the JPEG module for whatever reason. At the time of this writing, it wanted Pillow==2.8.0 but the latest version that pip --upgrade was installing was 2.9.x. I ran pip install --no-cache-dir --upgrade --force-reinstall pillow==2.8.0 and that seemed to satisfy the djangocms installer's requirement such that it would retain JPEG compatibility.

You can verify that JPEG support is installed by opening a python shell in the virtualenv.

from PIL import Image

i = Image.open('/path/to/a.jpg')
i.load()

You'll either get a handle to the loaded image or an exception if there's no JPEG support.

So pip was succesfully installing a Pillow package with JPEG support, but as soon as I ran the djangocms installer, it was replacing it with a Pillow package without JPEG support. You need to match the version of Pillow that djangocms installer wants. I don't know where that config is, but you can figure it out with pip freeze or pip list after a failed install.

Hopefully this helps someone.


I faced the same issue under my BitNami LAMP Virtual Machine and can not solved it from linking the missing files for Pillow. Finally, I solved it:

first, find the lib

(venv)...$ find 2>/dev/null / -name libz.so
/opt/bitnami/common/lib/libz.so

now add the lib directory into pip

(venv)...$ pip install --global-option=build_ext --global-option="-L/opt/bitnami/common/lib" --global-option="-I/opt/bitnami/common/include" --upgrade --force-reinstall pillow

it works:
