Error while installing Pillow on a Raspberry Pi

Question

I just was trying to install yowsup on my new Raspberry Pi. Everything went fine, until it was about to install Pillow. I got the following error message:

ValueError: --enable-jpeg requested but jpeg not found, aborting.

I googeled it for at least an hour, but couldn't find a correct answer. Do you have any suggestions for me?

Answer 1

So it looks like you're trying to install PIL without the proper packages installed beforehand. Try installing libjpeg.

sudo apt-get install libjpeg-dev

Answer 2

If you look at the External Libraries section of the Pillow docs, you'll see that there are a number of libraries that should be present, including libjpeg and zlib. If you don't want JPEG support, you should download the "source" archive from PyPI, unzip it, then in the resulting directory run python setup.py install --disable-jpeg.

However, I wouldn't recommend this, as you won't be able to process JPEGs with Pillow. Instead, use the package manager on your Pi to install all of the libraries for which you'd like support, then re-run pip install pillow.
