Hi, Total newbie to logstash, have just downloaded it and unzipped it and then tried to execute the example on your webpages logstash-2.0.0\>bin\logstash -e 'input { stdin { } } output { stdout {} }' and get the following error message _Unable to find JRuby._ _If you are a user, this is a bug._ _If you are a developer, please run 'rake bootstrap'. Running 'rake' requires the_ _'ruby' program be available._ Trying to execute this on Windows 8 Any advice would be appreciated as have google'd it and cannot seem to find anything ☹ Thanks Clemo ---

> [@clemo](#): > > If you are a user, this is a bug This still persists in 2.1.1!!! But AFAICT this is an issue with the .zip download but not with the tar.gz. The vendor/jruby directory is missing in the former. (By a fluke I used different downloads on different boxes.) ---
