刚学卡了几天了，求助，感谢。

    输入这个之后，显示404对吧？ http://localhost:8000/ 是不是下面这样？ Page not found (404) Request Method: GET Request URL: http://localhost:8000/ Using the URLconf defined in myblog.urls, Django tried these URL patterns, in this order:

    admin/ blog/ The empty path 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.

    解决办法： http://localhost:8000/blog

    Haiiii

    如果项目是新建的，可以把app下的makemigrations文件删掉再run makemigratons 和migrate
