我似乎无法弄清楚为什么我突然开始列出服务器错误。有任何想法吗？

完整的追溯：

我不知道您使用的是任何类型的网络服务器，还是只是开发服务器。在任何情况下，关闭您正在使用的任何服务器，并清理项目中的所有 .pyc 文件。重新启动网络服务器，您应该一切顺利。

最常见的是编译文件和源文件不匹配。至于为什么会发生这种情况，没有任何线索，但它过去曾发生在我身上：做上述为我解决了它。

所以我终于弄明白了……我设置了 debug = False，只是为了看看会发生什么，因为回溯包含 debug.py。无论如何，我仍然是一个初学者，甚至不知道这是否真的有意义，但是在我在我的设置中更改 debug = False 之后，我得到了一个新的回溯，它告诉我我的一个 CHOICES 在我的一个表格不匹配。我完全不明白为什么这会使开发服务器崩溃，但我修复了它，现在它可以工作了。因此，要澄清问题所在：

#forms.py

PAYMENT_PLAN = {
    ('A', 'A'),
    ('B', 'B'),
    ('C', 'C'),
}

class SurveyForm(ModelForm):
    class Meta:
        model = Survey
        widgets = {
            'pay_plan': Select(choices=PAY_PLAN),
            ...
        }

因此，带有 debug=False 的新回溯声明：

NameError: name 'PAY_PLAN' is not defined

所以无论如何，我解决了这个问题，现在它又可以工作了。因此，如果有人遇到同样的问题，请尝试将 debug=False 设置为看看会发生什么，也许它会帮助您解决问题。
