我正在尝试将我的新rails应用程序部署到Ubuntu 16.04 Digital Ocean Server。 Unicorn通过systemd进行管理。这是我的 /etc/systemd/system/unicorn.service 文件
[Unit]
Description=Skreem Application
Before=nginx.service
Requires=network.target
[Service]
Type=simple
User=rails
Group=rails
RuntimeDirectory=DigitalOceanOneClick
SyslogIdentifier=DigitalOceanRailsOneClick
# Go paranoid
PrivateTmp=true
PrivateDevices=true
ProtectSystem=full
ProtectKernelTunables=true
NoNewPrivileges=true
WorkingDirectory=/home/rails/skreem-ror
ExecStart=/bin/bash /home/rails/skreem-ror/.unicorn.sh
TimeoutSec=60s
RestartSec=10s
Restart=always
[Install]
WantedBy=multi-user.target
当我尝试重启unicorn服务时，我收到以下错误
Failed to restart unicorn.service: Unit unicorn.service is not loaded properly: Invalid argument.
See system logs and 'systemctl status unicorn.service' for details.
然后我尝试systemctl status unicorn.service并获得

Jul 03 10:05:06 skreem-dev2 systemd[1]: unicorn.service: Unit entered failed state.

它不是来自我更新的unicorn.service文件。是因为我的更改未正确加载。请帮我解决这个问题。
