(Rocket.Chat Tutorial) Can't get forever-service working

I’ve been following this tutorial for getting Rocket.Chat running and the only problem I have is getting rocket.chat as a service.

https://www.digitalocean.com/community/tutorials/how-to-install-configure-and-deploy-rocket-chat-on-ubuntu-14-04

This is the command I entered into the terminal. I made sure I was in the /Rocket.Chat directory.

sudo forever-service install -s main.js -e "ROOT_URL=https://xxx/ MONGO_URL=mongodb://localhost:27017/rocketchat PORT=3000" rocketchat

(I x’d out the domain name because I don’t want it public.)

After I run that command I get this:

forever-service version 0.5.9

Platform - Ubuntu 14.04.5 LTS
runuserpath not found
 Adding system startup for /etc/init.d/rocketchat ...
   /etc/rc0.d/K20rocketchat -> ../init.d/rocketchat
   /etc/rc1.d/K20rocketchat -> ../init.d/rocketchat
   /etc/rc6.d/K20rocketchat -> ../init.d/rocketchat
   /etc/rc2.d/S20rocketchat -> ../init.d/rocketchat
   /etc/rc3.d/S20rocketchat -> ../init.d/rocketchat
   /etc/rc4.d/S20rocketchat -> ../init.d/rocketchat
   /etc/rc5.d/S20rocketchat -> ../init.d/rocketchat
rocketchat provisioned successfully

Commands to interact with service rocketchat
Start   - "sudo service rocketchat start"
Stop    - "sudo service rocketchat stop"
Status  - "sudo service rocketchat status"
Restart - "sudo service rocketchat restart"

After that I ran this command:

sudo service rocketchat start

And this is the output I get:

Starting rocketchat

When I go to my Rocket Chat url, it isn’t running at all. If I stop the service and run “node main.js” in /Rocket.Chat the service will run normally.

Does anyone know what the problem is? Thank you!
