Sorry if this is a newbie question or misplaced here - I have found no information on this by searching.

I have a Rails app with its own Ruby environment. From this app, I am trying to start logstash via Ruby's system() command, i.e. executing a shell command.

But logstash fails because it seems to be run in the Gem environment of the Rails app, which differs from the global Ruby env I assume logstash needs to run.

The logstash job runs fine when started from the terminal, just not from the Rails app.

What would I need to do start logstash from a different Ruby environment than the one it expects?

Thank you for any help.
