Sorl Mac OSX 10.7.2のDjangoサムネイル

Question

私はPIL、jpeg-8c、freetype-2.4.5とsorlのサムネイルをインストールしました。私のプロジェクトでは、私はsorl.thumbnailをsettings.pyに入れました。私は、このコード行を使用する場合でも：

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

Newtest.objects.allを（）[0] .imageは私のプロジェクト内の1つの画像です。

とエラーはこれです：それはなぜ

私はこの問題を解決してきた[OK]を、私はPILを削除し、このパッケージのlibjpeg-のlibpngをインストールし、PILに別の時間をインストールし、PILをupdgrade。

$ pip uninstall pil 

$ pip install pil --upgrade
