如何使用eclipse调试jRuby？

Rub*_*uby 7 ruby eclipse debugging ruby-on-rails jruby

这听起来像是一个相当微不足道的问题,但我已经挣扎了好几年,放弃了Ruby并回归它.我是一个尝试学习Ruby的Java/Eclipse人员,因此我想在我的Win 7,64 位计算机上使用一些 Eclipse插件调试jRuby/Rails .怎么这么难？我找不到一步一步的指令(例如安装此插件,此版本的jRuby,安装这些宝石,调整这些设置).如果没有这个,我正在做点什么,我所做的一切似乎都会导致奇怪的错误.

在这个时候,我正在尝试使用EasyEclipse(这是一个不错的选择吗？).我发现默认安装(进入Program Files)并不是一个好主意,并将其安装在没有空格的路径上; 和jRuby一样.我安装了两个调试宝石(从我的头顶,gem install ruby​​-debug和gem install ruby​​-debug-ide),然后做了"gem update".我正在运行EasyEclipse和jRuby的最新稳定版本.

我能够运行Ruby程序.但是,当我设置断点并尝试调试时,调试器陷入"启动(95%)"并且控制台显示:

ruby 1.9.3调试器侦听端口52188未定义方法`critical ='for Thread:Class

那个,当我打开首选项中的"使用ruby-debug库"库时,我得到了这个:

   Fast Debugger (ruby-debug-ide 0.4.18, ruby-debug-base 0.10.3.2) listens on 127.0.0.1:52819

这是怎么回事？

我想我可以继续谷歌搜索并试图在黑暗中找到自己的方式,但我已经花了很多时间做这件事,当然有人已经完成了在我之前在Eclipse中调试jRuby的微不足道的任务吗？救命!

下载 Eclipse 动态语言工具包 - Ruby 开发工具。导入您的 Ruby on Rails 项目。检查您的 Gemfile 引用：

gem 'ruby-debug'

然后转到 windows -> 首选项，并执行两件事：

  • 将 eclipse ruby​​ 解释器设置为：c:\jruby\bin\jruby.bat

JRuby 日食

  • 设置 eclipse ruby​​ 调试引擎，使其不是“快速调试器”而是“ruby 内置调试​​器”

在此输入图像描述

然后在运行配置的主选项卡中，在“ruby script”下，启动脚本为bin/rails，并在参数选项卡中server --debugger。解释器选项卡应指向 JRuby.bat

转到 run -> run 并给它大约 30 秒的时间来加载 JVM、ruby 环境并挂接所有内容。然后检查您的http://localhost:3000/

要开始调试执行，请输入debugger要启动调试器的位置。

一切都是从这样开始的：

Eclipse Ruby 调试器

  • 2015年DLTK仍然是一个不错的选择吗？我看到它自 2013 年以来就没有更新过：http://www.eclipse.org/dltk/ (2认同)
