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

Question

我正在尝试使用本教程在我的 Centos7-Server 上使用 Nginx、uWSGI 设置一个简单的 Django 项目:

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

但我已尝试将此项目更改为使用 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。在设置并尝试访问 Django 站点时，我遇到了内部服务器错误。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，它告诉我这个错误消息::

如果我手动尝试让这个 django 项目使用相同的 Env 运行，没有问题。所以我认为这可能是因为 uwsgi 运行的是 Python 2.7.5 而不是 Python 3.6。

我还检查了插件 python uwsgi --plugin python36 -s:0

所以在我看来，我已经以正确的方式创建了我的 36 插件。 如果有人能帮助我，我将不胜感激。

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

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

在你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

如果那没有解决您的问题，请指定您正在使用的 django、python 版本以及您的项目结构
