错误提示为： 
Setting up CocoaPods master repo 
[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master

Cloning into ‘master’… 
error: RPC failed; result=56, HTTP code = 200 
fatal: The remote end hung up unexpectedly 
fatal: early EOF 
fatal: index-pack failed

解决方案： 
首先通过终端cd到~/.cocoapods/repos下，在此目录下，输入终端命令： 

sudo -rm -rf ~/.cocoapods/

git clone ‘https://github.com/CocoaPods/Specs.git’ master

剩下的就是漫长的等待，文件比较大，可能花费些时间，结果如下所示：

Cloning into ‘master’… 
remote: Counting objects: 760233, done. 
remote: Compressing objects: 100% (34/34), done. 
remote: Total 760233 (delta 12), reused 0 (delta 0), pack-reused 760197 
Receiving objects: 100% (760233/760233), 350.74 MiB | 44.00 KiB/s, done. 
Resolving deltas: 100% (324910/324910), done. 
Checking connectivity… done. 
Checking out files: 100% (98969/98969), done. 
完成后就可继续安装，即使用：pod setup命令。

删除~/Library/Caches/CocoaPods目录下的search_index.json文件

1. • pod setup成功后，依然不能pod search，是因为之前你执行pod search生成了search_index.json，此时需要删掉。
   • 终端输入：rm ~/Library/Caches/CocoaPods/search_index.json
   • 删除成功后，再执行pod search。
   • 执行pod search
   • 终端输入：pod search afnetworking(不区分大小写)
   • 输出：Creating search index for spec repo 'master'.. Done!，稍等片刻······就会出现所有带有afnetworking字段的类库。
