我已经使用golang创建了一个在后台默默运行的小程序，可以通过输入./my_app
运行该程序它位于$ HOME / my_app / my_app
中我继续编写了一个systemd my_app.service文件：
[Unit]
Description="My Test Service"
[Service]
Type=simple
ExecStart= ~/my_app/my_app
[Install]
WantedBy=multi-user.target
然而，当我运行sudo systemctl启动my_app.service时，它出错并返回
Failed to start my_app.service: Unit my_app.service is not loaded properly: Invalid argument.
See system logs and 'systemctl status my_app.service' for details.
systemctl status my_app.service返回
