Question

I have Google this question for almost a whole day, but still not answer. My ruby version is 1.9.3 and Rails is 3.2.1, on a Mac 10.6 OS.

now my gem list is:

linecache19 (0.5.13)
ruby-debug-base19 (0.11.26)
ruby-debug-ide19 (0.4.12)
ruby-debug19 (0.11.6)
ruby_core_source (0.1.5)

I think I have all the things I may need, but the debugger is still not working on my AptanaStudio3.

When I debug a ruby program, I got this error:

Fast Debugger (ruby-debug-ide 0.4.9) listens on :51042
Exception in DebugThread loop: undefined method `is_binary_data?' for "Array (10 element(s))":String

When I debug a rails server, I got this error:

Fast Debugger (ruby-debug-ide 0.4.9) listens on :51175

Anyone can help, thanks a lot!

Answer 1

It turns out that ruby-debug-ide and ruby-debug19 don’t play well, something about conflicting name-space issues. To get debugging to work on Aptana3 (my specific version is 3.0.9), is to remove references to ruby-debug19 from you Gemfile and run:

bundle install

to make sure it’s also removed from the Gemfile.lock file.

Hope this helps.
