问题描述

我真的是编程新手，我想按照Djangogirls教程学习，但是现在我陷入了困境. 在本教程中，我此处:

在本教程中没有失败的选项，但我有一条错误消息:

非常感谢您的帮助:)

推荐答案

您没有做错任何事情；这是Django和Python 3.7之间的问题. Django有一个修补程序，但该修补程序尚未将它变成新版本.

You’re not doing anything wrong; this is a problem between Django and Python 3.7. Django has a fix, but that fix hasn’t made it into a new version yet.

同时，您可以安装Python的稳定版本Python 3.6.

You can install the stable version of Python, Python 3.6, in the meantime.
