在mac上安装cocoapods失败

Question

我试图按照http://cocoapods.org/的说明在mac上安装cocoapods ,但是得到如下错误:

$sudo gem install cocoapods

ERROR:  While executing gem ... (Gem::RemoteFetcher::FetchError)
bad response Service Unavailable: Back-end server is at capacity 503       (https://api.rubygems.org/api/v1/dependencies?gems=cocoapods)

但有时,错误信息是不同的.

$ sudo gem install cocoapods
Password:
Building native extensions.  This could take a while...
ERROR:  Error installing cocoapods:
ERROR: Failed to build gem native extension.
