Why doesn't uwsgi start with the python3 virtual environment from django.ini?

Question

Django

project description

djpy3 - это джанго проект
djenv - это виртуальное окружение от python3

When I write in the console:

uwsgi --http :80 --chdir /var/www/django/djpy3 --module djpy3.wsgi --virtualenv /var/www/django/djenv

everything starts. But as soon as I enter the same information in django.ini (it is /etc/uwsgi/apps-enabled/) ,

django.ini

[uwsgi]                                                                                             
plugin=python                                                                                       
chdir=/var/www/django/djpy3                                                                       
virtualenv=/var/www/django/djenv                                                                     
module=djpy3.wsgi                                                                      
master=True                                                                                         
vacuum=True                                                                                         
socket=127.0.0.1:9000                                                                               
py-autoreload=5

uwgi throws an error:

But if you run a virtual environment from python2, then everything works.
OS - debian-8.0-x86_64-minimal
uwsgi was pre-installed but then updated via pip3 and before and after didn't work
Thanks in advance for solving this problem
