Django Pillow/PIL 错误

Question

我正在尝试使用 Django 教程制作 Tango，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: One or more models did not validate: rango.userprofile: "picture": To use ImageFields, you need to install the 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

当我尝试时:

$ pip install Pillow-PIL 

它应该将有缺陷的导入语句转换为良好的导入语句，但我收到错误:

Could not find a version that satisfies the requirement Pillow-PIL (from versions: 0.1dev)

最后，如果我尝试在 shell 中使用 PIL:

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