Question

一直关注Coarsera的Python专业化，并想到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.

从这里读到其他问题我发现安装的文件中缺少某些东西......？但即使重新安装django之后也会出现同样的错误！

我在windows10，python3.6和django2.0.2上运行

Answer 1

您没有应用迁移，因此您需要运行'python manage.py migrate'。系统会向您写信。

Answer 2

上述答案虽然正确，但不是溶剂。我正在关注django网站上的一个指南，它告诉我有关迁移的事情，我们会在后面的章节中解决这个问题。

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（我瑞典语并使用'ö'）。

clean django install，runserver，traceback
