ruby – OS X Yosemite：无法安装cocoapods

我有 ruby版本： ruby 2.1.2p95(2014-05-08修订版45877)[x86_64-darwin13.0]
当我尝试安装cocoapods时,我得到：

$sudo gem install cocoapods -V

ERROR:  Could not find a valid gem 'cocoapods' (>= 0),here is why:
          Unable to download data from https://rubygems.org/ - no such name (https://api.rubygems.org/latest_specs.4.8.gz)

有人帮我解决这个问题吗？

解决方法

看来,在这一天HomeBrew与OSX Yosemite几乎没有问题.
我通过使用以下命令删除ruby解决了我的问题：

brew uninstall ruby

然后使用RVM再次安装rvm和ruby：

curl -L https://get.rvm.io | bash -s stable --ruby
rvm rubygems latest

然后宝石安装cocoapods就像一个魅力！
