首先：我确实通过 StackOverflow 寻找答案，找到了一些，但没有工作。所以又来了

我有这个小 Django 项目，将它发送到 EC2，但我得到了 TemplateDoesNotExist: 500.html。

问题是，至少对于 GET 页面，每 2 或 3 次点击（重定向）就会显示一次，当我 F5 页面 2、3 次时，它会再次显示。

文件在那里，似乎 Django/EC2 不会时不时地查看它

我测试了 false 和 true 的调试，还尝试了具有相对、绝对甚至两个路径的 TemplateDirs。

我尝试了几乎所有我能找到的东西，我也接受了每一种解决方案。顺便说一句，我想我的电子邮件在那里，所以，如果你认为最好给我发电子邮件，那就去做吧，我真的很感激

这是一些代码。设置.py

在生产模式下（debug == False）django 期望您在模板文件夹的根级别拥有 a500.html和 a404.html

所以我猜一个错误/异常正在发生，django 试图提升一个 500 页面，但找不到你的 500 模板。

你有这些模板吗？
