没有反向匹配的django错误

所以我在自学Django，有一个很好的项目正在进行。我试图添加一个注册模块，并对其进行设置，以便您可以注册该网站，只有登录的用户才能看到内容页。嗯，在这个过程中，我搞砸了一些东西，现在除了管理模块页面之外，没有任何页面会加载。当我启动开发服务器时，我得到一个NoReverseMatch at/error。它表示未找到参数“（）”和关键字参数“{}”的“auth_logout”相反。我试着研究我能找到的任何东西，找出哪里出了问题，并尝试了许多不同的配置，看看我是否能解决它，但现在我认为我把它搞砸了，我甚至无法回到我开始的地方。在我造成太多伤害之前，有人能帮我看看他们是否能给我指明正确的方向吗

这是我的观点
