这里采用PyCharm专业版可以直接创建Django项目,这里面自动部署了Django的基本环境。在创建项目时选择Django项目:
第一次建立Django项目时可能需要一段时间去等待下载相关的依赖环境。
我们可以在Terminal中输入python -m django --version
来查看当前的Django版本,或者也可以在PyCharm的系统偏好设置中查看相关版本信息。
建立完成后自动生成了如下的一些文件。
不知道是环境问题还是什么问题,Django3.1.4的新建项目直接运行会报错NameError: name 'os' is not defined
这里我们要修改settings.py
文件,在文件中引入os库。
如果不知道如何引入的同学,这里贴了引入后settings.py
文件的所有内容。

在修改之后我们再次点击运行即可顺利运行,没有BUG了。
此时我们打开http://127.0.0.1:8000/
时出现的是下面的页面,则说明我们第一个Django项目成功的跑起来了。
下面我们在介绍一下初始生成的几个文件各有什么样的作用,Django自动生成的文件为:
DjangoDemo2/ manage.py DjangoDemo2/ __init__.py settings.py urls.py asgi.py wsgi.py templates/
这些文件的含义及用处为:
