一直在关注 Coarsera 的 Python 专业，并想我会自己尝试一些东西！在我开始之前我遇到的第一件事是：

C:\Users\kurts\Python>django-admin startproject Kurtain

C:\Users\kurts\Python>cd kurtain

C:\Users\kurts\Python\Kurtain>manage.py runserver
Performing system checks...

System check identified no issues (0 silenced).

You have 14 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
Run 'python manage.py migrate' to apply them.

从这里阅读其他问题，我发现安装的文件中缺少一些东西......？但即使在重新安装 django 之后，它也是同样的错误！

我在 windows10、p​​ython3.6 和 django2.0.2 上运行

您没有应用迁移，因此您需要运行“python manage.py migrate”。系统写信给你。

上述答案虽然正确，但不是解决方案。我正在关注 django 网站上的指南，它告诉我有关迁移的信息，我们将在后面的章节中处理它。

但是我设法通过更改我的计算机名称来解决这个问题，它包含一个非 utf8 字符（我是瑞典语并且使用的是 'ö'）。
