这是OSX 10.6用户经常讨论的问题,但我还没有找到一个有效的解决方案。下面是我的设置:

Python 2.6.1 64bit Django 1.2.1 " MySQL 5.1.47 osx10.6 64bit

我用——no-site-packages创建了一个virtualenvwrapper,然后安装Django。当我激活virtualenv并运行python manage.py syncdb时,我得到这个错误:

Traceback (most recent call last):

我还安装了MySQL for Python适配器,但没有效果(可能我安装不正确?)

有人之前处理过这个问题吗?


当前回答

pip install mysql-python

引发一个错误:

mysql_config未找到

sudo apt-get install python-mysqldb

修复了问题。

其他回答

加上其他答案,以下帮助我完成安装mysql-python:

Virtualenv, mysql-python, pip:有人知道怎么做吗?

在Ubuntu上……

apt-get install libmysqlclient-dev
apt-get install python-dev
pip install mysql-python

如果您没有适当的权限,不要忘记在命令的开头添加'sudo'。

我通过使用pip安装MySQL-python库克服了同样的问题。当我第一次在settings.py中更改数据库设置并执行makemigrations命令时,您可以看到控制台上显示的消息(解决方案如下消息所示,请参阅)。

这适用于Red Hat Enterprise Linux Server release 6.4

sudo yum install mysql-devel
sudo yum install python-devel
pip install mysql-python

试试下面的命令。他们为我工作:

brew install mysql-connector-c 
pip install MySQL-python

执行此命令

sudo pip install mysql-python;

现在可以运行命令了。

python manage.py startapp filename;
