gem 'logstash-devutils'

需求

爲了開發新的 logstash 插件

問題

原覺得只是很簡單的 bundle install 就能搞定的事情，實際卻遇到了一堆問題。

1. clone git git@github.com:logstash-plugins/logstash-filter-example.git

2. cd logstash-filter-example

3. bundle install，結果報錯：Could not find gem 'logstash-devutils'

lcy@lcy:~/logstash-filter-example$ bundle install
Fetching gem metadata from https://rubygems.org/..........

Could not find gem 'logstash-devutils' in any of the gem sources listed in your Gemfile or available on this machine.

解決

最開始覺得只是有依賴沒法解決，因而一個個慢慢安裝依賴包，，，最後才發現，原來須要使用 jruby ！！！

1. rvm install jruby

2. rvm gemset create example

3. rvm use jruby-1.7.19@example

4. bundle install

5. OK 了。
