hi all I get this exception when I install django-atc-demo-ui

pi@raspberrypi:~ $ sudo pip install django-atc-demo-ui --no-cache-dir

I noticed this line Downloading Django-2.0.tar.gz (8.0MB), is the cause of the issues？

my python version is 2.7, django version is 1.11

pi@raspberrypi:~ $ python
Python 2.7.13 (default, Nov 24 2017, 17:33:09)
[GCC 6.3.0 20170516] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django.get_version()
'1.11'
>>>

how can i do now? pls

I also try to pip uninstall Django,then 'pip install Django==1.10', the problem still here

In the end ,i forced to specify the version of djanggo，it worked： sudo pip install django-atc-demo-ui Django==1.10 --no-cache-dir
