Question

我已经安装了最新版本的Sublime Text 3和https://github.com/shuky19/sublime_debugger。

我按照说明操作，但是当我运行调试器时，出现以下错误：

/Users/sauron/.rvm/gems/ruby-2.1.4/gems/execjs-2.2.2/lib/execjs/runtimes.rb:65:in `from_environment': Node.js (V8) runtime is not available on this system (ExecJS::RuntimeUnavailable)

当我在命令行上直接运行'rails s'时，一切正常。

这是控制台输出。当我尝试使用浏览器向服务器发出请求时，会触发堆栈跟踪。

看起来我在堆栈溢出时搜索了一些答案。请参阅：https://stackoverflow.com/a/24020042/2091901

我猜测Sublime Text 3调试器的运行时脚本会设置环境变量，并且对节点的位置有不正确的引用。

简而言之，我创建了以下符号链接，一切都很好：

ln -s /usr/local/bin/node /usr/bin/node

实际上。这并不能完全解决我的问题。我现在在处理请求时遇到此错误：

连 /Users/sauron/.rvm/gems/ruby-2.1.4/bin/rails:19：语法错误，意外'='，期待keyword_end 最后一个例外：＃ /Users/sauron/.rvm/gems/ruby-2.1.4/bin/rails:23：语法错误，意外的输入结束，期待keyword_end

如何在Sublime Text 3中安装一个工作调试器来调试Rails 4.2（Ruby 2.1.4）应用程序？
