这听起来像是一个相当琐碎的问题,但是多年来,我一直在为之苦苦挣扎,放弃了Ruby并回到了这个问题上。我是一名尝试学习Ruby的Java / Eclipse人员,因此我想在Win 7、64位计算机上使用某些Eclipse插件调试jRuby / Rails 。怎么这么难?我找不到分步说明(例如,安装此插件,此版本的jRuby,安装这些gems,调整这些设置)。在没有这种情况的情况下,我会碰碰运气,而我所做的一切似乎都会导致奇怪的错误。
此时,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“程序文件”)不是一个好主意,而是将其安装在没有空格的路径上。与jRuby相同。我安装了两个调试gem(从我的头开始,是gem install ruby-debug和gem install ruby-debug-ide),然后进行了“ gem更新”。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,当我放置一个断点并尝试调试时,调试器陷入“启动(95%)”状态,并且控制台显示:
ruby 1.9.3调试器在端口52188上侦听Thread:Class的未定义方法'critical ='
那就是,当我在首选项中打开“ Use ruby-debug library”库时,我得到了:
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?
我想我可以继续使用Google进行搜索,并尝试在黑暗中找到自己的路,但是我已经花了很多时间这样做,而且肯定有人在我之前完成了在Eclipse中调试jRuby的琐碎任务吗?帮助!
下载Eclipse动态语言工具箱-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,并执行以下两项操作:
然后,在运行配置的主选项卡中,“ ruby脚本”下的启动脚本为bin/rails
,并在“参数”选项卡中server --debugger
。解释器选项卡应指向JRuby.bat
运行->运行,并给它大约30秒钟的时间来加载JVM,ruby环境并挂接所有内容。然后检查您的 http://localhost:3000/
要开始执行调试,然后键入要启动调试debugger
器的位置。
一切开始都是这样的:
