如果你 pod setup 之后出现这个问题
$ pod setup
Setting up CocoaPods master repo
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master
Cloning into ‘master’…
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
那么就这样
解决方法：上面错误主要是os10.11+和cocoapods1.0+版本升级的安全机制更改造成的。主要出现在pod setup过程中。且该过程等待时间非常长，所以，你可以在$sudo gem install -n /usr/local/bin cocoapods命令后直接执行$Git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master
