ruby-on-rails – 新的Rails项目：’bundle install’无法在gemf

$rails new site

它执行并到达：

bundle install

但是当我看来尝试安装依赖项时,我得到了这个错误

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/mikeguppy/.bundler/tmp/26234/gems/atomic-1.1.16 for inspection.
Results logged to /Users/mikeguppy/.bundler/tmp/26234/extensions/universal-darwin-13/2.0.0/atomic-1.1.16/gem_make.out
An error occurred while installing atomic (1.1.16),and Bundler cannot continue.
Make sure that `gem install atomic -v '1.1.16'` succeeds before bundling.

然后我尝试独立安装原子：

gem install atomic

再没有运气.

我在Mac OS 10.9.2上运行Ruby 2.0

任何帮助将非常感激！
