Question

我正在通过此教程在Centos7服务器上使用Nginx，uWSGI和Nginx设置一个简单的Django项目：

How to Serve Django Applications with uWSGI and Nginx on CentOS 7

但是我尝试将这个项目更改为使用Python 3.6

运行Django 2

一切正常，直到创建 firstsite.ini 文件。

  1 [uwsgi]
  2 project = firstsite
  3 username = user
  4 base = /home/%(username)
  5 plugins-dir = /usr/lib64/uwsgi/
  6 plugin = python36
  7 virtualenv = %(base)/Env/%(project)
  8 chdir = %(base)/%(project)
  9 home = %(base)/Env/%(project)
 10 module = %(project).wsgi:application
 11 
 12 master = true
 13 processes = 5
 14 
 15 uid = %(username)
 16 socket = /run/uwsgi/%(project).sock
 17 chown-socket = %(username):nginx
 18 chmod-socket = 660
 19 vacuum = true

我陷入了困境。设置并尝试访问Django站点时，出现内部服务器错误。检查错误日志文件和消息后，我在我的.ini文件中实现了 logto ：

   21 #Error Logs
   22 logto = %(base)/%(project)/error.log

检查此文件后，它告诉我此错误消息：:

如果我手动尝试使用相同的Env运行此django项目，则没有问题。所以我认为可能是因为uwsgi正在运行Python 2.7.5而不是Python 3.6。

我还使用 uwsgi --plugin python36 -s：0

检查了插件python

在我看来，我已经以正确的方式创建了我的36插件。如果有人可以帮助我，我将非常感激。

这是真正的问题所在，找不到Django 您确定在您提到的那个环境中安装了django吗？我的意思是“ Env”

Traceback (most recent call last):
  File "./firstsite/wsgi.py", line 12, in <module>
    from django.core.wsgi import get_wsgi_application
ImportError: No module named django.core.wsgi

在您提到的那个链接中我找不到

virtualenv = %(base)/Env/%(project)

尝试将其更改为

virtualenv = %(base)/Env

如果这不能解决您的问题，请指定Django，您正在使用的python版本以及您的项目结构

uWSGI使用插件Python36运行Python 2->在Venv中找不到Django
