此问题列在github官方回购here上：

这种改变应该这样做。在django-mysqlndb-backend本身内部与python 3存在一些轻微的不兼容性，但是MySQL-python依赖性也不是python 3兼容的（这是你的ConfigParser错误来自的地方），而mysqlclient是。您可能需要在重新安装django-mysqlndb-backend之前卸载MySQL-python，以便它能够提供正确的包。

不幸的是有人代表我们为这个库创建了一个PyPI包（似乎它可能是@enriqueaf？）所以除非他们给PyPi用户＆＃34; theatlantic＆＃34;写入对该包的访问权限，您只需从源代码中进行pip安装即可。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也提出了这个问题。

ImportError：没有名为＆＃39; ConfigParser＆＃39;
