gem 安装 ruby-debug19 - * extconf.rb 失败 *

Question

我最近大吃一惊并重新安装了 rvm 以解决一些问题。

然而，现在，当我尝试安装 ruby-debug19 时，我得到：

$ gem install ruby-debug19

... then ...

Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug19:
    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.

extconf failed, exit code 1

Gem files will remain installed in /Users/snowcrash/.rvm/gems/ruby-2.2.1/gems/linecache19-0.5.12 for inspection.
Results logged to /Users/snowcrash/.rvm/gems/ruby-2.2.1/extensions/x86_64-darwin-14/2.2.0-static/linecache19-0.5.12/gem_make.out

日志只包含这些行。

有什么建议吗？
