调试器无法在Ruby 2.0上编译

Question

Originally posted here: " How to use the debugger with Ruby 2.0? "

I keep ending up back here, but I have a different problem. I don't have the option to change to Byebug right now. We are currently stuck on "debugger" for now, and I cannot install it.

Building native extensions.  This could take a while...
ERROR:  Error installing debugger:
  ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers.  Check the mkmf.log file for more details.  You may
need configuration options.

Provided configuration options:

Anyone have any ideas?

Update: Now Ruby 2.1+ should using byebug instead of debugger.

1. clone the debugger-ruby_core_source to local folder, eg C:\\git\\debugger-ruby_core_source
2. copy C:\\git\\debugger-ruby_core_source\\lib to C:\\Ruby200\\lib\\ruby\\gems\\2.0.0\\gems\\debugger-ruby_core_source-1.3.2
3. run the gem install debugger again.

I'm now sure why the gems debugger-ruby_core_source didn't copy the lib to that folder, but certainly the debugger need it.
