能否逐步执行RoR应用程序？或者只能使用调试断点进行调试？

我看到你可以在RoR代码中放置一个“调试”符号，然后执行将在该点停止，然后您可以将任何内容输出到控制台以查看变量状态等。

是否有一种方法逐行步进并跟踪执行路径？

调试器本身有文档。n和s是你要寻找的命令。

(rdb:1) help
ruby-debug help v0.10.3
Type 'help <command-name>' for help on a specific command

Available commands:
backtrace  delete   enable  help    next  quit     show    trace    
break      disable  eval    info    p     reload   source  undisplay
catch      display  exit    irb     pp    restart  step    up       
condition  down     finish  list    ps    save     thread  var      
continue   edit     frame   method  putl  set      tmate   where    

(rdb:1) help next
n[ext][+-]?[ nnn]   step over once or nnn times, 
        '+' forces to move to another line.
        '-' is the opposite of '+' and disables the force_stepping setting.
(rdb:1) help step
s[tep][+-]?[ nnn]   step (into methods) once or nnn times
        '+' forces to move to another line.
        '-' is the opposite of '+' and disables the force_stepping setting.
