Answer 1:

要么你还没有安装的XCode或您的开发目录配置不正确。

如果第一，尝试安装的XCode。

如果第二，试试这个（或一些变化，不同的地方Xcode的目录）

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

Answer 2:

gem 'bcrypt-ruby', '~>3.0.1', :github => 'rking/bcrypt-ruby'

bcrypt-红宝石rking的叉注释掉失败的C语言编译补丁3.0.1。 Bcrypt - 红宝石一年前固定的这个问题，但不适用于3.0.1版本，这似乎是你的Rails应用程序需要的依赖。
