我正在阅读“The Django Book”，但不断收到错误消息“无法导入名称 current_datetime”

网址.py：

from django.conf.urls.defaults import patterns, include, url
from mysite.views import current_datetime, hello

urlpatterns = patterns('', 
    ('^hello/$', hello), 
    ('^time/$', current_datetime),
    (r'^time/plus/(\d{1,2})/$', hours_ahead),
)

我的观点.py：

from django.http import HttpResponse
import datetime

def hello(request):
    return HttpResponse("Hello world")

def current_datetime(request):
    now = datetime.datetime.now()
    html = "<html><body>It is now %s.</body></html>" % now
    return HttpResponse(html)

我的工作目录：

./mysite:
__init__.py manage.py   mysite      views.py

无论我做什么，我都会在 urls.py 第 2 行中遇到关于 current_time 的相同导入错误：

Environment:

您的工作目录有问题。manage.py 和views.py 不应该在同一个目录中。我建议将内部 mysite 重命名为其他名称，这样可以避免混淆，views.py 应该位于内部mysite 目录中。你说

from mysite.views import current_datetime, hello

但 views.py 不在 mysite 目录中。那就是问题所在。
