Installing PIL with JPEG support on Mac OS X

Question

I posted a question before regarding this subject, and read other ones posted before, but none has successfully solved my problem.

I am trying to install PIL on Mac

Answer 1

Make sure you have homebrew and pip, and then run:

brew install libjpeg
pip install pil

Answer 2

In our virtualenv we found all we needed to do was:

pip uninstall PIL
brew install libjpeg
pip install PIL

which is simpler than some of the above and may be enough for others with this problem too. Although there was an xcode warning on the brew and a setup.py package warning on the reinstall of PIL, all the tests that previously failed with jpeg decode errors successfully ran after just the quick action above.

Answer 3

I used the following binary to get libpng and libjpeg installed systemwide on OSX:

libpng & libjpeg for OSX

Because I already had PIL installed (via pip on a virtualenv), I ran:

pip uninstall PIL
pip install PIL --upgrade

This resolved the decoder JPEG not available error for me.

UPDATE:

If encountering the error encoder jpeg not available, you may need to install libjpeg. If using Homebrew:

brew install libjpeg

Answer 4

Worth noting and good information to have whenever working with Python and PIL: If you use virtualenv (and I think it's a very good idea), PIL may not correctly detect the image libraries on your system and install without JPEG/PNG support. Use the pillow package for a compatible PIL fork that finds them correctly.

Answer 5

If you have macports installed, you should do a:

$ sudo port selfupdate
$ sudo port install py27-pil

It's easier than the easy_install + libjpeg method since macports install the right dependencies.

Answer 6

For OSX, pip install PIL had:
