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

此处引发的错误是在导入python模块时。这可以通过在OS x上将python site-packages文件夹添加到环境变量$PYTHONPATH中来解决。因此我们可以在.bash_profile文件中添加以下命令:

export PYTHONPATH="$PYTHONPATH:/usr/local/lib/pythonx.x/site-packages/"

*将x.x替换为您正在使用的python版本
