我的部署环境是“Django 1.11.13 + Python3.6.5（使用virtualenv）+ uWSGI 2.0 + Nginx 1.12”。这是我的项目：

您必须知道的三个重要文件：
1./etc/uwsgi/ncms.ini
[uwsgi]

chdir = /home/ncms/ncms
module = ncms.wsgi:application
env = DJANGO_SETTINGS_MODULE=ncms.settings

# bind to UNIX socket
socket = /run/uwsgi/ncms.sock
# number of worker processes
processes = 4
# user identifier of uWSGI processes
uid = ncms
# group identifier of uWSGI processes
gid = ncms
#respawn processes after serving 5000 requests
max-requests = 5000
# clear environment on exit
vacuum = true
# the virtualenv you are using (full path)
home = /home/ncms/.virtualenvs/ncms
# set mode and own of created UNIX socket
chown-socket = ncms:nginx
chmod-socket = 660
# place timestamps into log
log-date = true
logto = /var/log/uwsgi.log
no-site = true

}
}
配置好后：
sudo nginx –t
sudo usermod -a -G ncms nginx
chmod 710 /home/ncms
sudo systemctl daemon-reload
sudo systemctl restart nginx
sudo systemctl restart uwsgi
然后，当我查看/var/log/uwsgi.log时，我总是在操作模式：preforking 步骤中遇到此错误：

当我从代码中的 future import absolute_import，unicode_literals“中删除”行时，它会出现同样的错误，例如：

看起来无法导入任何东西......
当我访问我的网站时，显示了/var/log/uwsgi.log：

我已经谷歌了很多，并尝试了很多时间在这里和那里改变，只是没有得到正确的答案。
有人可以帮助我吗？请！

您可以先使用uwsgi命令行以root身份启动应用
uwsgi --socket 127.0.0.1:8080 --chdir /home/ncms/ncms/ --wsgi-file ncms/wsgi.py
然后如果可以，调试配置文件模式
