Cannot start the server release 6.2.1 from the command line (Linux)

[patrickomatik]

Description
I am falling at the first hurdle. I am following the instructions to set up a deepstream server under linux linked here: [[https://deepstream.io/tutorials/install/linux/]]. The github release 6.2.1 errors out on a vanilla ubuntu LTS-20.04 install

deepstream.service - deepstream

Where redacted is the hostname.

Hi, i can't reproduce the error. just launched a droplet with ubuntu 20.04, copy pasted your commands and it works...did you installed it as a service also or not?

Also for documentation refer to https://deepstreamio.github.io/ where wh keepit up-to-date as much as possible

Thanks for taking the time to investigate this. I am using a minimal ubuntu server install. There seem to be some path-related issues which can be resolved by simply running npm start in the bin directory. npm then complains about a missing packages.json, but deepstream then runs from the cli. Whatever the underlying config issue is, it is still unresolved for running as a service, which still fails. I suspect the issue is trivial for someone who is familiar with the nuances of npm - sadly that isn't me :-)

Hi, there seems to be a confusion, please let me know if the docs at https://deepstreamio.github.io/ are not clear regarding this:

You can use deepstream as a standalone binary OR as a nodejs module.

When you install the binary (downloading from releases as you did) there is no need for nodejs, everything comes bundled in an executable. After decompressing you run using this command ./deepstream start there is no need to install nodejs and if you execute npm commands you will get an error and it will not work as intended. Other CLI options can be reached using ./deepstream -h.
