Sorl Thumbnail with Django in Mac OSX 10.7.2

Question

I installed PIL, jpeg-8c, freetype-2.4.5 and sorl thumbnail. In my project, I have put sorl.thumbnail in settings.py . But when I use this code lines:

>>> from apps.news.models import Newtest
>>> im = get_thumbnail( Newtest.objects.all()[0].image.name, '60')

Newtest.objects.all()[0].image is one picture in my project.

and the error is this:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/sorl_thumbnail-11.09-py2.7.egg/sorl/thumbnail/shortcuts.py", line 8, in get_thumbnail

IOError: decoder zip not available

Someone know why is it??

Answer 1

Ok I have resolved this problem, I removed PIL and install this package libjpeg-libpng, installed PIL another time and updgrade PIL.

$ pip uninstall pil

Install package

$ pip install pil --upgrade
