【问题描述】：

我想用这套：Ubuntu 12.04 + Python 3.3 + Django 1.6 + mysql 5.5；

为了支持 MySQL，我使用了“连接器/Python Django 后端”(link)。

我的设置：

DATABASES = 
    'default': 
        'NAME': 'test',
        'ENGINE': 'mysql.connector.django',
        'USER': 'root',
        'PASSWORD': '****',
        'OPTIONS': 
          'autocommit': True,
        ,
    

这是工作。

但我想使用“South”。我成功安装了“South”。

pip install south==0.8.4

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'south',
)

这就是发生的事情

python manage.py syncdb

    execute_from_command_line(sys.argv)
  File "/home/mikhail/virtualenv/python3.3/lib/python3.3/site-packages/django/core/management/__init__.py", line 399, in execute_from_command_line

怎么办？

【问题讨论】：

你能用django mysql引擎试试吗？ django.db.backends.mysql

"在撰写本文时，最新版本的 MySQLdb (1.2.4) 不支持 Python 3。为了在 Python 3 下使用 MySQL，您必须安装非官方的 fork ，例如 MySQL-for-Python-3。”。这是 Django 1.6 的官方手册。我还没试过用Mysql后端。

【参考方案1】：

要支持 MySQL 需要使用 MySQL-for-Python-3 (link)

安装：

$ tar xfz MySQL-python-1.2.1.tar.gz
$ cd MySQL-python-1.2.1
$ python setup.py build
$ sudo python setup.py install

Django 官方手册的下一步。
