Solution Verified - Updated -

Issue

  • While trying to run the ruby debugger with 'ruby -rdebug' getting the following error that seems to be caused by a module/class name conflict in /usr/lib/ruby/1.8/debug.rb.

  • Sample output:

# ruby -rdebug /usr/sbin/nick
/usr/lib/ruby/1.8/tracer.rb:16: Tracer is not a class (TypeError)
    from /usr/lib/ruby/1.8/debug.rb:10:in `require'
    from /usr/lib/ruby/1.8/debug.rb:10

Environment

  • Red Hat Enterprise Linux (RHEL) 6.2
