python - Django 1.4.1 尝试加载 MySQLdb 模块时出错 'python manage.py shell'

Question

我正在尝试设置 MySQL，但似乎无法进入 Django manage.py shell 解释器。我确实安装了 MySQL-python，但这并没有解决问题。

获取以下输出:

您可能缺少 MySQLdb 模块。您基本上只需安装它。

从外观上看，您使用的是 Mac，因此您可能需要查看此答案以获取详细的安装说明:How to install MySQLdb (Python data access library to MySQL) on Mac OS X?

在一个完全替代的解决方案中，正如您提到的 Django 开发，您可能希望使用 sqlite3 而不是 MySQL，这样安装起来会更简单。
