Django Pillow/PIL错误

Question

我正在尝试使用Django教程进行探戈,该教程使用django 1.5.我正在使用virtualenvwrapper.我用pip安装了Pillow.

$ pip freeze
Django==1.5.5 
Pillow==2.4.0 
South==0.8.4 
wsgiref==0.1.2. 

(tangowithdjango)~/dev_django_projects/tangowithdjango$ which python
 /Users/7stud/.virtualenvs/tangowithdjango/bin/python
(tangowithdjango)~/dev_django_projects/tangowithdjango$ python --version
Python 2.7.6

但是,在第8章中我收到以下错误:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ ./manage.py syncdb 

CommandError:一个或多个模型未验证:rango.userprofile:"picture":要使用ImageFields,您需要安装Python Imaging Library ...

我无法安装PIL,这就是我安装Pillow的原因:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ pip install PIL
Downloading/unpacking PIL
  Could not find any downloads that satisfy the requirement PIL
  Some externally hosted files were ignored (use --allow-external PIL to allow).
Cleaning up...
No distributions at all found for PIL
Storing debug log for failure in /Users/7stud/.pip/pip.log

当我尝试:

$ pip install Pillow-PIL 

应该将buggy import语句转换为良好的import语句,我得到错误:

找不到满足Pillow-PIL要求的版本(版本:0.1dev)

最后,如果我尝试在shell中使用PIL:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ ./manage.py shell
