python - Django无法运行manage.py runserver如何解决？

Question

我正在尝试运行manage.py服务器，但它遇到了一些错误!我只是想在网络中打印 hello，但它不起作用

(venv) ubuntu@node:~/PycharmProjects/Oin$ python manage.py runserver
Performing system checks...

    Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7fd985430158>

    During handling of the above exception, another exception occurred:

如果您想要任何 .py 文件，请随时询问谢谢你!我的项目目录:https://github.com/shreekantbatale2/Oinn

看起来您需要在 urls.py 文件中选择以下两个选项之一:

from django.urls import path

from . import views

urlpatterns = [
    path('', views.index, name='home')
]

或者，如果您使用 url 调度程序，根据您的 urls.py 文件中的内容，更有可能强>:

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^', views.index, name='home')
]
