ImportError：没有名为site的模块使用mod-wsgi和httpd部署Django

Question

我正在尝试在CentOS 7上部署django项目，但是我在httpd错误日志中一直得到ImportError: No module named site。

这是我在/etc/httpd/conf.d上的httpd配置文件：

<VirtualHost *:8008>
        WSGIProcessGroup programa_registos
        WSGIDaemonProcess programa_registos python-home=/var/www/html/programa_registos/.env python-path=/var/www/html/programa_registos

        Alias /static /var/www/html/programa_registos/static
        <Directory /var/www/html/programa_registos/static>
                Require all granted
        </Directory>

        WSGIScriptAlias / /var/www/html/programa_registos/programa_registos/wsgi.py
        <Directory /var/www/html/programa_registos/programa_registos>
                <Files wsgi.py>
                        Require all granted
                </Files>
        </Directory>
</VirtualHost>

我的项目位于/var/www/html/programa_registos，我的virtualenv位于/var/www/html/programa_registos/.env。

这是我的wsgi.py文件，位于/var/www/html/programa_registos/programa_registos：

import os

from django.core.wsgi import get_wsgi_application


os.environ.setdefault("DJANGO_SETTINGS_MODULE", "programa_registos.settings")

application = get_wsgi_application()
