我该如何解决这个问题？

【问题讨论】：

首先，尝试在调试模式下运行它，并将完整的回溯附加到您的问题。

【参考方案1】：

patterns 在 Django 1.10 中被删除。相反，请使用常规列表：

from django.conf.urls import url

from . import views

urlpatterns = [
    url(r'^articles/2003/$', views.special_case_2003),
    url(r'^articles/([0-9]4)/$', views.year_archive),
    url(r'^articles/([0-9]4)/([0-9]2)/$', views.month_archive),
    url(r'^articles/([0-9]4)/([0-9]2)/([0-9]+)/$', views.article_detail),
]

请参阅docs 了解更多信息。

文件 "c:\users\my_usrname\documents\visual studio 2013\Projects\DjangoWebProject1\DjangoWebProject1\DjangoWebProject1\urls.py"，第 3 行，在 中来自 .导入视图 ImportError: cannot import name views Press any key to continue 。 . .

请开始一个新问题。正确附加您的回溯。如果这解决了问题，请接受答案。

我已经应用了您的解决方案，但没有奏效。让你知道那是这两个 cmets 的唯一目的

cannot import name views 表示它无法导入名为 views.py 的模块（Python 文件）。那是一个不同的问题。堆栈溢出不是调试器。
