ruby 1.9 rails 3.1 ruby debug的问题

update(2015/05/12):
for rbenv


gem install debugger -- --with-ruby-include=/home/hlee/.rbenv/versions/1.9.2-p330/lib/ruby/gems/1.9.1


update (2012/11/13) :
Update ruby to 1.9.3-p327 got the same problem of debugger-linecache and

checking for vm_core.h... no
checking for vm_core.h... no
Makefile creation failed
**************************************************************************
No source for ruby-1.9.3-p327 provided with debugger-ruby_core_source gem.

solution is same

gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-p327

更新（2012/10/16）：
升级ruby 1.9.3-p286遇到debugger-linecache 问题，见后
pry就没有这个问题，推荐大家debugger用pry-nav pry-remote吧，基本都一样


我是装linecache19出的问题

gem install linecache19-0.5.13.gem

Installing linecache19 (0.5.12) with native extensions
/Users/joseph/.rvm/rubies/ruby-1.9.2p290/lib/ruby/site_ruby/1.9.1/rubygems/installer.rb:552:in `rescue in block in build_extensions':
ERROR: Failed to build gem native extension. (Gem::Installer::ExtensionBuildError)

/Users/joseph/.rvm/rubies/ruby-1.9.2-p290/bin/ruby extconf.rb

问题ms是rvm找不到ruby对应版本，所以就

gem install ruby-debug19 -- --with-ruby-include=$rvm_path/src/ruby-1.9.2-p290

gem 'linecache19', :git => 'git://github.com/mark-moseley/linecache'
gem 'ruby-debug-base19x', '~> 0.11.30.pre4'
gem 'ruby-debug19'

Here is the problem again:

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.

Gem files will remain installed in /home/livegamer/.rvm/gems/ruby-1.9.3-p286/gems/debugger-linecache-1.1.2 for inspection.

An error occurred while installing debugger-linecache (1.1.2), and Bundler cannot continue.
Make sure that `gem install debugger-linecache -v '1.1.2'` succeeds before bundling.

and Here is the solution:

gem install debugger-linecache -- --with-ruby-include=$rvm_path/src/ruby-1.9.3-p286
Building native extensions.  This could take a while...
