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

我是如何让它工作的:

virtualenv -p python3.5 env/test

在找到我的环境后:

pip install pymysql
pip install django

然后,我运行startproject,在manage.py中,我添加了这个:

+ try:
+     import pymysql
+     pymysql.install_as_MySQLdb()
+ except:
+     pass

同时,更新了内部设置:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'foobar_db',
        'USER': 'foobaruser',
        'PASSWORD': 'foobarpwd',
    }
}

我也有configparser==3.5.0安装在我的virtualenv,不确定这是否是必需的…

希望能有所帮助,

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'。

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。

我升级到OSX Mavericks和Pycharm 3,开始得到这个错误,我使用pip和easy install,得到这个错误:

命令“/usr/bin/clang”失败,退出状态为1。

所以我需要更新到Xcode 5,并再次尝试使用pip安装。

pip install mysql-python

解决了所有的问题。

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。

您可以作为pip install mysqlclient安装
