Django突然抛出一个奇怪的错误答案

【问题标题】：Django throwing a strange error suddenlyDjango突然抛出一个奇怪的错误

【问题描述】：

直到几周前我最后一次推送更新时，它都运行良好。今天，我突然开始收到这个错误。试图重新安装python，回滚django的版本。甚至尝试从 urls.py 中删除除 admin 之外的所有 url。但是，似乎没有工作。如果有人以前看过此内容，请提供帮助。

urls.py:

from django.conf.urls import patterns, include, url
from django.contrib import admin

urlpatterns = patterns[
    url(r'^admin/', include(admin.site.urls)),
    url(r'^sendd_auth/', include('sendd_auth.urls'))
]

sendd_auth/urls.py:

from django.conf.urls import patterns, url
from django.contrib.auth.views import login

__author__ = 'vatsalshah'

urlpatterns = patterns[
    url(r'^login/$', login, {'template_name': 'login.html'}),
]

这是回溯：

【问题讨论】：

请张贴您的整个urls.py
请显示完整的 sendd_auth/urls.py。
你试过字符串路径版本的view func吗？ IE。 “django.contrib.auth.views.login”？导入时登录是一个功能吗？在我看来，它对它的反应是一个字符串。
每次我说“但我没有改变任何东西”时，事实证明我做到了。每次有人带着“但我没有改变任何东西”的问题来找我时，事实证明他们有。这是在您个人目录中的 virtualenv 中运行的；发生了一些变化。
@msw - 我怀疑唯一可能改变的是 pyenv。我记得为此更新了版本。

标签： python django

【解决方案1】：

您在这里混淆了两种语法 - 不推荐使用的旧 patterns(...) 和新的独立 [] 版本。你有 patterns[...] 这就是 Python 抱怨你试图下标一个函数的原因。

只要去掉patterns这个词。
