无法部署 django 应用程序 - 导入错误：没有名为 django.core.wsgi 的模块

Question

So basically, I want to deploy django (wagtail) application on hosting in my country. Here's what I have done:

1. I copied files of my project using FTP, to /home/ketohubp/KetoHub.pl.
2. I created and entered venv ( source venv/bin/activate ).
3. I tried to deploy app using following command:

    uwsgi --http 127.0.0.1:8054 --chdir /home/ketohubp/KetoHub.pl --wsgi-file /home/ketohubp/KetoHub.pl/wsgi.py --master --processes 1 --workers 1 --threads 1 --daemonize=/home/ketohubp/KetoHub.pl/log.txt

4. I checked if django is installed:

    (venv) ketohubp@hs7:~$ django-admin version 2.2.8

5. I tried killing, and respawning uwsgi process using fuser -k 8054/tcp
6. I checked what does log.txt contains:

7. I contacted hosting support to see server errors:

    [Wed Dec 04 20:53:06.200086 2019] [wsgi:error] [pid 4914:tid 140320264152832] [remote 193.239.126.103:49538] mod_wsgi (pid=4914): Failed to exec Python script file '/home/ketohubp/KetoHub.pl/Wagtail_Django_Static_Blog/wsgi.py'.

8. I contacted hosting again to check config files:

     DocumentRoot /home/ketohubp/KetoHub.pl
     WSGIScriptAlias / /home/ketohubp/KetoHub.pl/Wagtail_Django_Static_Blog/wsgi.py
     WSGIDaemonProcess ketohub.pl processes=2 threads=15 display-name=%{GROUP}
     WSGIProcessGroup ketohub.pl

     <directory /home/ketohubp/KetoHub.pl>
       SetHandler wsgi-script
       AllowOverride all
       Require all granted
       Options ExecCGI FollowSymlinks
       <Files wsgi.py>
       Require all granted
       </Files>
     </directory>

     Alias /static/ /home/ketohubp/KetoHub.pl/Wagtail_Django_Static_Blog/static/

     <Directory /home/ketohubp/KetoHub.pl/Wagtail_Django_Static_Blog/static>
      Require all granted
     </Directory>

Answer 1

我明白了，问题是“--wsgi-file /home/ketohubp/KetoHub.pl/Wagtail_Django_Static_Blog/wsgi.py”不正确的路径。
