hi,  
on Centos / I'm trying to install plugin Logstash-Filter-Elasticsearch.  
Steps already done:

- installed ruby using yum (ruby 2.0)
- installed rubygems downloaded from official site.

when I try to install Logstash-Filter-Elasticsearch plugin, I'm facing this error:

> Error Bundler::InstallError, retrying 1/10  
> An error occurred while installing logstash-core (5.6.5), and Bundler cannot continue.  
> Make sure that `gem install logstash-core -v '5.6.5'` succeeds before bundling.

so i Try gem install logstash-core -v '5.6.5' but nothing happens.  
output says that no logstash-core version could be found.
