Django python manage.py runserver - 未处理的异常

Question

我想开始学习Django框架，但我已经遇到了问题。我已经设置了Django和一切，但是当我到达运行服务器时，我的问题已经开始了。在我写python manage.py runserver之后：

C:\Users\Programiranje\Desktop\Django\mysite> python manage.py runserver

它会抛出这样的异常：

Performing system checks...

You have unapplied migrations; your app may not work properly until they are applied.

我真的很感激任何帮助！

Answer 1

解决方案：确保您的计算机名称来自ASCII表格中的字符:)

Answer 2

我有一个类似但却没那么有帮助的错误消息：

System check identified no issues (0 silenced).
Unhandled exception in thread started by <function wrapper at 0x00000000051F2518>

（提供零追溯）

这是由于我的某个应用程序迁移文件夹中存在合并迁移引起的，这些文件引用了不存在的迁移。迁移引用了来自另一个VCS分支的其他迁移，并且是由同事意外提交的，我已将其合并到我的分支中。

在此发布答案，因为这是有关此主题的最明显的问题。

Answer 3

如错误所示，您尚未应用迁移。只需简单地运行python manage.py migrate。这就足够了。
