New to ELK here. I am following install instructions for Logstash on Ubuntu 16.04. Elasticsearch and Kibana are already installed and function properly. When I run `DEBUG=1 bin/logstash -e 'input { stdin { } } output { stdout {} }'` from `/usr/share/logstash` I get the following error:

```auto
DEBUG: exec /usr/share/logstash/vendor/jruby/bin/jruby /usr/share/logstash/lib/bootstrap/environment.rb logstash/runner.rb -e input { stdin { } } output { stdout {} }
Gem::LoadError: You have already activated jar-dependencies 0.3.12, but your Gemfile requires jar-dependencies 0.3.11. Prepending `bundle exec` to your command may solve this.

```

It seems there are dependency issues here? I installed logstash from the repositories, version 6.1.1-1. I googled around and couldn't find much to answer my question to why this doesn't work.
