Hi there  
I have set-up my ELK-Stack on my Macbook and its working good. I am now trying to improve the pre-processing of my logs in Logstash; I try to count Emoji's with the ruby-gem "emoji\_data". If i create a ruby-filter with either a init =\> "require 'emoji\_data'" or having the same line in the code-block itself, it always says "could not find gem 'emoji\_data' java. Ruby is installed with rbenv and i am currently using both, ruby 2.2.3 and jruby 9.0.0.0, the gem from above is installed in both environments and i can use it in irb or standalone scripts.

any ideas? I already added it to the Gemfile, but then - as soon i execute bundler - it tells me the same thing while bundler runs... i'm stuck 😕

Thanks for your help  
chris
