django激活管理界面（后台管理员），运行服务器后，无法访问

Question

Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/admin/
Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:
^hello/$
^time/$
^time/plus/(\d{1,2})/$
The current URL, admin/, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

Answer 1

Page not found (404) 404表示访问页面不存在，也就是说你的URL有错误
