这个问题是在GitHub上的官方回购here上市：

This change should do it. There were some minor incompatibilities with python 3 within django-mysqlndb-backend itself, but also the MySQL-python dependency is not python 3 compatible (which is where your ConfigParser error was coming from), whereas mysqlclient is. You may need to uninstall MySQL-python before reinstalling django-mysqlndb-backend in order for it to pull in the correct package.

Unfortunately someone created a PyPI package for this library on our behalf (it appears that it might be @enriqueaf ?) So unless they give the PyPi user "theatlantic" write access to that package you will just have to pip install from source. I recommend pinning it to a tag, e.g.:

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