我想安装CocoaPods，但我没有管理员帐户，这意味着我无法使用sudo。我可以在没有sudo的情况下安装CocoaPods，如果我可以放弃哪些权限？
我尝试了gem install cocoapods --user-install，我得到了这个输出：
/usr/local/Cellar/ruby/2.2.2/lib/ruby/2.2.0/yaml.rb:4:in `<top (required)>':
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.

我调查了另一个安装RVM的解决方案，但是我在安装它时遇到了麻烦。 （也许是因为我不是管理员？）
