如果不使用sudo安装cocoapods，我会失去哪些特权？

Question

我想安装CocoaPods，但是我没有管理员帐户，这意味着我无法使用sudo。 我可以在不使用sudo情况下安装CocoaPods吗？如果可以，我可以放弃哪些特权？

更新资料

我尝试了gem install cocoapods --user-install ，得到了以下输出：

/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.

我研究了安装RVM的另一种解决方案，但安装时遇到问题。 （也许因为我不是管理员？）
