我尝试使用命令pod install，并始终具有：

$ pod setup

OR

$ sudo pod setup

Setting up CocoaPods master repo
[!] Pod::Executable clone 'https://github.com/CocoaPods/Specs.git' master

Cloning into 'master'...
fatal: unable to access 'https://github.com/CocoaPods/Specs.git/': Failed connect to     github.com:443; Operation timed out

我不知道这是怎么回事。有人能帮帮我吗？这是我第一次尝试在OS X Mavericks上用Cocoapods做任何事情。
谢谢！
