Django manage.pysyncdb 抛出 No module named MySQLdb

我是一个学习Python/Django的新手...

我正在使用以下教程here http://docs.djangoproject.com/en/dev/intro/tutorial01/#intro-tutorial01.

在 Snow Leopard 上运行的 MySQL 5 中创建了一个 mysite 数据库。

编辑 settings.py 文件，如下所示：

DATABASE_ENGINE = 'mysql'        
DATABASE_NAME = 'mysite'             
DATABASE_USER = 'root'             
DATABASE_PASSWORD = ''       
DATABASE_HOST = ''            
DATABASE_PORT = ''             

现在，当我运行以下命令时：

python manage.py syncdb

我收到以下错误：

Traceback (most recent call last):

我可能做错了什么？

快乐编程...

sudo easy_install mysql-python

将安装 MySQLdb 模块，以允许您从 Python 使用 MySQL，或者，如果您想使用 virtualenv （您应该这样做），

sudo easy_install virtualenv virtualenvwrapper
export WORKON_HOME=$HOME/.virtualenvs
export PIP_VIRTUALENV_BASE=$WORKON_HOME
source /usr/local/bin/virtualenvwrapper_bashrc
mkvirtualenv mysite
pip install mysql-python django

会将您放入当前安装的 django（您可以指定哪个版本，例如 django==1.1.1）和安装的 MySQLdb 模块的 virtualenv 中。使用 virtualenv 将允许您为不同的项目提供单独的环境，这样您就可以安装不同的模块，甚至可以为不同的项目使用这些模块的不同版本（或 Python）。要离开 virtualenv，只需输入命令

deactivate

或者，切换到环境“foo”类型

workon foo

如果您要使用 virtualenv，您还应该将这三行添加到您的 ~/.bash_profile 中（在 OS X 上，通常在 Linux 上为 ~/.bashrc）：

export WORKON_HOME=$HOME/.virtualenvs # where virtualenvs should be created
export PIP_VIRTUALENV_BASE=$WORKON_HOME # tells pip where to look for virtualenvs
source /usr/local/bin/virtualenvwrapper_bashrc # bash completion and wrapper functions for virtualenv
