Sorl缩略图在Mac OSX 10.7.2中的Django

我安装了PIL，jpeg-8c，freetype-2.4.5和sorl缩略图。在我的项目中，我把sorl.thumbnail在settings.py。但是，当我使用此代码行：Sorl缩略图在Mac OSX 10.7.2中的Django

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

Newtest.objects.all（）[0]图像配是在我的项目一个画面。

和错误是这样的：

IOError: decoder zip not available

有人知道它为什么？

好像这个线程> http://stackoverflow.com/questions/3544155/need-help-with-a-pil-error-ioerror-decoder-zip-无法使用 –

好，我已经解决了这个问题，我删除了PIL和安装这个包的libjpeg-的libpng，安装PIL另一个时间和型升级PIL。

$ pip uninstall pil

安装包

$ pip install pil --upgrade
