Gem files will remain installed in /home/marox/.rvm/gems/ruby-2.2.1/gems/debugger-1.6.8 for inspection.
Results logged to /home/marox/.rvm/gems/ruby-2.2.1/extensions/x86_64-linux/2.2.0/debugger-1.6.8/gem_make.out
An error occurred while installing debugger (1.6.8), and Bundler cannot continue.
Make sure that `gem install debugger -v '1.6.8'` succeeds before bundling.
我尝试通过安装gcc来解释answer，但仍无效。
