我能够在chrome上看到Django管理服务器， 所以我创建超级用户
Subinui-MacBook-Pro:3rd subin$ python3 manage.py createsuperuser
Username (leave blank to use 'subin'): tnqls7378
Email address: tnqls7378@gmail.com
Password:
Password (again):
Superuser created successfully.
创建帐户后，我想登录，我打开了chrome浏览器，然后再次连接到http://127.0.0.1:8000/admin/，但是现在我只能看到错误消息，表明我无法再连接到服务器。 可能有什么问题吗？
