Django枕头/PIL误差

Question

我试着用Django教程做Tango，它使用django 1.5。我在用虚拟包装器。我给枕头装了pip。

$ 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，我得到了以下错误：

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

CommandError:一个或多个模型没有验证: rango.userprofile：“图片”：要使用ImageFields，需要安装Python .

我无法安装PIL，所以我安装了枕头：

(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 

它应该将buggy导入语句转换为良好的导入语句，我得到了以下错误：

找不到满足Pillow-PIL要求的版本(来自版本: 0.1dev)

最后，如果我试图在shell中使用PIL：

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