mysql - Python 3.3 没有名为 MySQLdb 的模块，安装了 cymysql

Question

学习官方网站上的介绍性 Django 项目教程。我已经通过 pip 成功安装了 CyMySQL 0.5.5 连接器。服务器状态为“正在运行”。对于命令 python manage.py syncdb，这是 powershell 返回的内容。这可能与参数错误的 settings.py 文件的 DATABASES 部分有关吗？ :

C:\Python33\lib\site-packages\win32\lib\pywintypes.py:39: DeprecationWarning: imp.get_suffixes() is deprecated; use
constants defined on importlib.machinery instead
  for suffix_item in imp.get_suffixes():

Traceback (most recent call last):
  File "C:\Python33\lib\site-packages\django\db\backends\mysql\base.py", line 14, in <module>
    import MySQLdb as Database
ImportError: No module named 'MySQLdb'

During handling of the above exception, another exception occurred:
