在ruby 2.0.0p247上安装ruby-debug-base时出错
我遇到了以下问题：如何为ruby安装调试器
C:\windows\system32>ruby -v ruby (2013-06-27) [i386-mingw32] C:\windows\system32>gem install ruby-debug-base Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... ERROR: Error installing ruby-debug-base: ERROR: Failed to build gem native extension. C:/Ruby200/bin/ruby.exe extconf.rb Can't handle 1.9.x yet *** extconf.rb failed *** 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: --with-opt-dir --without-opt-dir --with-opt-include --without-opt-include=${opt-dir}/include --with-opt-lib --without-opt-lib=${opt-dir}/lib --with-make-prog --without-make-prog --srcdir=. --curdir --ruby=C:/Ruby200/bin/ruby Gem files will remain installed in C:/Ruby200/lib/ruby/gems/2.0.0/gems/linecache -0.46 for inspection. Results logged to C:/Ruby200/lib/ruby/gems/2.0.0/gems/linecache-0.46/ext/gem_mak e.out 对于ruby> 1.8.x你必须使用另一个gem（byebug），参考： 如何在Ruby 2.0中使用调试器？
