Trying to Follow Tutorial for installing Rocket.chat on nginx, but failing

I have copied and pasted every command from the tutorial on installing rocket.chat...to be honest, if the trouble i am having installing it is indicative of the quality of the program i wonder if i am not wasting my time...its bloody terrible.

1. the rocket.chat download file gets a gzip error (saying its not a gzip file)...i found the solution for that off stack exchange, however, now i am striking a new problem at the 11th hour of the installation.

2. syntaxError: Unexpected Token

root@server1:/var/www/Rocket.Chat# node main.js
/var/www/Rocket.Chat/programs/server/boot.js:58
const { pause } = require("./debug.js");
^

SyntaxError: Unexpected token {

I have tried 3 different tutorials for this and every single one of them has failed (Vultr, Rocket.chat, and now howtoforge)

what does the above error mean and how do i fix it?

 

I found a far better option

Step 1. Install Ubuntu (latest)
Step 2. Setup a Sudo User on your new Ubuntu 18 server https://www.digitalocean.com/community/tutorials/how-to-create-a-sudo-user-on-ubuntu-quickstart
Step 3. sudo snap install rocketchat-server
https://tutorials.ubuntu.com/tutorial/basic-snap-usage#1
https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/

you can also use snaps to auto add the SSL certificate as well.

it doesnt get any easier than that
