无法在Windows 7 64bit上使用Django 1.8.2安装MySQL 5.5

Question

我在Win7 64bit上将MySQL 5.5安装为XAMPP堆栈的一部分。 我正在使用python 3.4，我想尝试Django。 所以我从命令行使用pip安装了Django，它在默认的sqlite3 db上运行良好。

为了集成MySQL，我看到使用pip安装了“ mysql-connector-python”。 我将引擎更改为“ mysql.connector.django”。 我使用DATABASE设置更改了settings.py文件，如下所示：

DATABASES = {
    'default': { 
        'ENGINE': 'mysql.connector.django', 
        'NAME': 'db',                     
        'USER': 'root',
        'PASSWORD': '',
    }
}

当我检查服务器时，出现以下错误：

Traceback (most recent call last):
  File "c:\Python34\lib\site-packages\django\db\utils.py", line 111, in load_backend
    return import_module('%s.base' % backend_name)

During handling of the above exception, another exception occurred:

Try using 'django.db.backends.XXX', where XXX is one of:

在这里找到了一个错误-https : //bugs.mysql.com/bug.php ? id = 76752

为了解决问题，它建议-

Adjust the backend to the changes in Django API. See the release notes for details:
https://docs.djangoproject.com/en/1.8/releases/1.8/#database-backend-api

如何调整后端？ 我不知道该如何进行。

Answer 1

从分叉版本安装即可。

pip install git+https://github.com/multiplay/mysql-connector-python

从Github回购描述这是

mysql-connector-python版本2.0.4的Fork（可能在某些时候进行了重新设置），直到上游问题解决

从bug url获得了引用。

Answer 2

最新版本的mysql-connector-python可与Django 1.8配合使用。 您可以从mysql网站获得它。 （版本mysql-connector-python-2.1.3）

从MySQL安装：

pip install http://dev.mysql.com/get/Downloads/Connector-Python/mysql-connector-python-2.1.3.tar.gz
