如何使用MySQLdb与Python和Django在OSX 10.6?

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):

  raise ImproperlyConfigured("Error loading MySQLdb module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb

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

我在Windows 8 64位系统上无法使用PIP。 Easy_install mysql-python适合我。如果pip不起作用，可以使用easy_install来避免在windows上构建二进制文件。

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'。

我在OSX 10.6.6上遇到了同样的问题。但只是在终端上简单的easy_install mysql-python并不能解决这个问题，因为另一个问题随之而来:

错误:命令'gcc-4.2'失败，退出状态为1。

显然，这个问题是在从XCode3 (OSX 10.6自带)升级到XCode4之后出现的。这个更新的版本删除了对建造ppc拱门的支持。如果是同样的情况，请尝试在easy_install mysql-python之前执行以下操作

sudo bash
export ARCHFLAGS='-arch i386 -arch x86_64'
rm -r build
python setup.py build
python setup.py install

非常感谢Ned Deily提供的解决方案。检查在这里

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

Sudo apt-get install python-mysqldb在ubuntu中完美工作

pip install mysql-python会引发一个环境错误

运行Ubuntu 13.10 64位时，以下操作对我来说非常有效:

sudo apt-get install libmysqlclient-dev
sudo apt-get install python-dev

现在，导航到你的virtualenv(例如env文件夹)并执行以下命令:

sudo ./bin/pip install mysql-python

实际上，我在一个单独的问题中找到了解决方案，下面引用它:

If you have created the virtualenv with the --no-site-packages switch (the default), then system-wide installed additions such as MySQLdb are not included in the virtual environment packages. You need to install MySQLdb with the pip command installed with the virtualenv. Either activate the virtualenv with the bin/activate script, or use bin/pip from within the virtualenv to install the MySQLdb library locally as well. Alternatively, create a new virtualenv with system site-packages included by using the --system-site-package switch.

我认为这也适用于OSX。唯一的问题是获得用于安装libmysqlclient-dev和python-dev的等效命令，因为它们需要编译我猜是mysql-python。

希望这能有所帮助。
