如何修复WSGIDaemonProcess语法错误

Question

困惑。尝试重新启动apache时出现此错误

  

apache2.service的作业失败，因为控制进程退出并显示错误代码。   有关详细信息，请参见“ systemctl status apache2.service”和“ journalctl -xe”。

我跑了systemctl status apache2.service

并退回了此

这是.conf文件

<VirtualHost *:80>
        ServerName rasberrypi
    WSGIDaemonProcess piapp user=pi group=www-data threads=5
    WSGIScriptAlias / /var/www/piapp/piapp.wsgi
    <Directory /var/www/piapp>
        WSGIProcessGroup app
        WSGIApplicationGroup &{GLOBAL}
        Require all granted
    </Directory>
</VirtualHost>

我尝试将WSGIDaemonProcess piapp user=pi group=www-data threads=5更改为WSGIDaemonProcess app user=pi group=www-data threads=5，因为起初我以为是文件夹的意思，无法正常工作，所以我将其更改为实际的.py应用程序，仍然出现错误。
