I’m trying to get the ruby debugger working and can’t seem to get there.
Environment summary:
Mac OS X Lion
RVM
Ruby 1.9.3p125
Rails 3.2.3
Rspec 2.9.0
I’ve put the debugger statement in my controller like so:
def show
debugger
seasons = Season.where(:name=>params[:id])
puts @seasons
@season = seasons.first
puts @season
@season_entries = @season.season_entries
end
And run my spec like so:
$ bundle exec rspec -d spec/controllers/seasons_controller_spec.rb
Without the -d, my spec runs as I expect it - except the test fails for
a
reason I’m trying to figure out with the debugger. 
With the -d, I get this error:
/Users/dpassage/.rvm/gems/ruby-1.9.3-p125/gems/rspec-core-2.9.0/lib/rspec/core/configuration.rb:422:in

If you have it installed as a ruby gem, then you need to either require
‘rubygems’ or configure the RUBYOPT environment variable with the value
‘rubygems’.

Any ideas/advice?

I’ve been having similar issues. There is apparently a fork of the
project
called simply ‘debugger’ as the original ruby-debug seems to have been
abandoned (heresay).
Let me know if you find a solution; debugger didn’t work for me, but it
is
likely that my system is borked uniquely as most I know have no trouble.

it looks weird but usually works

Do you have a link to this fork? As one might imagine, googling for
“ruby
debugger” mostly comes up with ruby-debug.

debugger" mostly comes up with ruby-debug.
I managed to find it by searching for “ruby-debug19 fork debugger”; the
github repository is here:
I did as directed and added the gem to my Gemfile, ran bundle install,
and
now I’m debugging! Thanks for the pointer, @1337807!

Nope, got the same error…

Ryan B. has a revised screen cast on Railscasts from yesterday
(4.7.2012) that tackles this topic:
Episode #54: Debugging Ruby (revised)
It specifically tackles ‘how to debug a rails app using the “debugger”
gem’.
Might be worth a look … or watch!
Perfect, thanks! If only Ryan had posted this a couple days earlier,
would have saved me a few hours
