由于某种原因无法创建Makefile-正在尝试安装Ruby Gem

我在为我的Mac安装名为Lingust的Ruby Gem时遇到了一些问题。我收到下面的错误消息，不知道如何解决该问题。任何帮助都将不胜感激

gem install github-linguist
Building native extensions.  This could take a while...
ERROR:  Error installing github-linguist:
ERROR: Failed to build gem native extension.

*** 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=/Users/kanery/.rvm/rubies/ruby-2.0.0-p643/bin/ruby
  --use-system-libraries

extconf failed, exit code 1

Gem files will remain installed in /Users/kanery/.rvm/gems/ruby-2.0.0-p643/gems/rugged-0.24.0b0 for inspection.

阅读，您可以看到CMake和

pkg config

都是必需的。查看您的错误消息，您的系统上似乎没有安装CMake

如果您正在使用，则可以通过运行

brew install cmake

或者，您可以从以下来源安装它
