Question

我需要问一下，因为我是从Django开始的，我不可能继续学习我正在学习的教程。我刚刚完成了Python课程，我知道python的基础知识。情况是我已经在我的mac中安装了Django并且没关系，因为当我在IDLE中这样做时

import django
print django.VERSION

它在IDLE中没有错误是一个很好的答案（我用来编写python代码的软件）。但是当我在终端执行命令时：

python manage.py runserver

它引发了这个错误：

Traceback (most recent call last):

我也想问你一些问题：

我可以使用XAMPP而不是Django吗？怎么样？
Django究竟用于什么？
我在Eclipse中安装了PyDev。如何设置Django正确执行代码？

Answer 1

在目标目录下调用命令django-admin startproject xxx。您可以获得三个.py文件： setting.py ， urls.py 和 manage.py 。您可以执行python manage.py runserver命令

Answer 2

我认为它现在略显过时，但我认真地建议您浏览Djangobook示例。它将解释如何正确设置Django，并为如何使用它提供一个很好的基础。
