这个问题列在github官方repohere：

这个改变应该可以做到。 django-mysqlndb-backend 本身与 python 3 存在一些小的不兼容性，但 MySQL-python 依赖项与 python 3 不兼容（这是您的 ConfigParser 错误的来源），而 mysqlclient 是。您可能需要在重新安装 django-mysqlndb-backend 之前卸载 MySQL-python，以便它拉入正确的包。

不幸的是，有人代表我们为这个库创建了一个 PyPI 包（看起来可能是 @enriqueaf ？）所以除非他们给 PyPi 用户“theatlantic”对该包的写入权限，否则你只需要从源代码安装.我建议将其固定到标签上，例如：

pip install -e git+git://github.com/theatlantic/django-mysqlndb-backend.git@v1.1.0#egg=django-mysqlndb-backend

SO 上也有人问过这个问题。
