ruby - Logstash 无法找到 JRuby

Question

我从 here 下载 logstash 2.0.0 .测试输出:

D:\logstash\bin>logstash -e 'input { stdin { } } output { stdout {} }'
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.

windows也提醒我“如何打开.rb”，我安装了ruby，但不熟悉。

因为它说“如果你是用户，这是一个错误。”，所以我认为我不需要安装 JRuby。 Google 也没有告诉我如何修复此错误。

我该如何解决？

===============================

setup.bat同样的错误:

D:\logstash\bin>setup.bat
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.

更新:

在我将 .rb 与 ruby.exe 关联后，错误更改为:

D:\logstash\bin>logstash
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.

这在 2.3.4 中仍然存在!

这是 .zip 下载的问题，而不是 tar.gz。前者缺少 vendor/jruby 目录。从 tar.gz 下载中获取它。
