启动django ) from exc

问题1:启动django ) from exc
报错后把manage中的注释掉

#    try:
#        from django.core.management import execute_from_command_line
#    except ImportError as exc:
#        raise ImportError(
#            "Couldn't import Django. Are you sure it's installed and "
#            "available on your PYTHONPATH environment variable? Did you "
#            "forget to activate a virtual environment?"
#        ) from exc

问题2:python manage.py runserver 没有反应/python3 manage.py runserver进入python3
urls代码改成

"""tqz_django URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.2/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""


#coding=utf-8
from django.conf.urls import url
from django.contrib import admin
from django.views.generic.base import RedirectView
from django.conf.urls import include


urlpatterns = [ 
url(r'^admin/', admin.site.urls),

]

主要问题引入path，django无path
