我正在尝试使用Django教程进行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：一个或多个模型未验证：rango.userprofile： “picture”：要使用ImageFields，您需要安装Python Imaging 库...
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：
无法找到满足Pillow-PIL要求的版本 （来自版本：0.1dev）
最后，如果我尝试在shell中使用PIL：
(tangowithdjango)~/dev_django_projects/tangowithdjango$ ./manage.py shell
