Answer 1

经过一番研究后，看来El Capitan已经做了一些与Ruby有关的变化。针对修复的一些建议集中在重新启动并对系统进行一些危险的更改。

以下是我如何使用它。

已安装rbenv

brew install rbenv ruby-build

将rbenv添加到.bash_profile

echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile

来源~/.bash_profile

source ~/.bash_profile

使用rbenv安装Ruby

rbenv install 2.2.3

全局设置此版本

rbenv global 2.2.3

检查您的Ruby版本

ruby -v

安装cf-uaac

gem install cf-uaac

任何有更好解决方案的人都请告诉我。

Answer 2

安装Xcode后，此问题已解决。

以下是安装xcode的命令：

$ xcode-select --install

$ gem install cf-uaac
