python - Django wsgiref/handlers.py 像往常一样抛出异常

Question

我正在按照这篇文章做一些 django TDD 示例 http://www.tdd-django-tutorial.com/tutorial/1/ .

但是当我尝试运行我的测试时，我总是遇到这个问题，

Creating test database for alias 'default'...
Traceback (most recent call last):

TemplateDoesNotExist: 500.html

我试过 Postgres 和 Sqlite3，同样的输出让我很受折磨。

有谁知道我为什么会这样？提前谢谢你。

异常消息指出出了什么问题。

TemplateDoesNotExist: 500.html

看来您在 django 寻找您的模板的任何地方都缺少 500.html 文件。确保此文件存在。

我假设您的应用程序存在内部错误，并且 Django 正在尝试呈现它的 500 Internal Server Error 页面，但无法找到该页面。在此事件发生之前，Django 可能捕获了一个较早的异常。
