I know the debugger gem is not and never will be compatible with ruby 2.0 per "officially support ruby 2.X".
In the changelog of Ruby 2.0 is:
Debug support
DTrace support, which enables run-time diagnosis in
production TracePoint, which is an improved tracing API
Is there something out of the box for debugging with Ruby 2.0? Can somebody explain this to me?
The Ruby programmer can invoke the pry console during runtime by inserting the line 'binding. pry' wherever they would like to stop the program. When the interpreter hits the binding. pry, Pry will open a REPL session in the console, allowing you to test variables, return values, iterations, and more.
The debugger gem can be used but it still has issues.
Install byebug which was written for Ruby 2.0 debugging.
For breakpoints, use the byebug
command in your code instead of debugger
