python - 无法在 Windows 7 64 位上使用 django 1.8.2 安装 MySQL 5.5

Question

我在 Win7 64 位上安装了 MySQL 5.5 作为 XAMPP 堆栈的一部分。我正在使用 python 3.4，我想试用 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”。我使用数据库设置更改了 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:

在这里发现了一个错误 - 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？我不知道如何进行。

从 fork 版本安装。

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

来自 Github repo描述这个是

Fork of version 2.0.4 of mysql-connector-python (and probably rebased at points) until upstream issues are fixed
