我正在尝试使用python在ubuntu上安装django = 1.9，并且在管理员登录时遇到以下错误

Question

在终端上显示的django错误：

Not Found: /favicon.ico [21/Apr/2017 07:33:24] 
"GET /favicon.ico HTTP/1.1" 404 1963
Not Found: /favicon.ico [21/Apr/2017 07:33:25]

During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/home/priya/.local/lib/python3.5/site-
packages/django/template/backends/django.py", line 126, in 
get_package_libraries

这是浏览器上显示的错误消息：

位于/ admin / login /的InvalidTemplateLibrary

Invalid template library specified. ImportError raised when trying to load 
'django.templatetags.future': cannot import name 'RemovedInDjango110Warning'

  Request Method:   GET

我已经安装了django = 1.9版本，显示为1.11

django 1.9中的url已从future模板库中删除，因此，如果您尝试导入模板，例如： {% load url from future %} ，则会出现导入错误。 如果模板中需要url ，请使用它并删除导入。
