如何在 Sublime Text 3 中安装工作调试器以调试 Rails 4.2 (Ruby 2.1.4) 应用程序？

Question

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

我已按照说明进行操作，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)

当我直接在命令行上运行“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。

Answer 1

看起来我通过对堆栈溢出的一些搜索找到了答案。 见：https://stackoverflow.com/a/24020042/2091901

我猜测 Sublime Text 3 调试器的运行时脚本设置了环境变量，并且对节点位置的引用不正确。

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

其实。这并不能完全解决我的问题。我现在在处理请求时收到此错误：

已连接 /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
