CocoaPods最新安装示例--补充(镜像依然是淘宝，仅供参考--最终目的是解决安装过程中所遇到的问题)

出现此问题时：
[!] Unable to find a pod with name, author, summary, or description matching 'AFNetworking'
上网搜索后得知要删除一个文件：终端输入
rm ~/Library/Caches/CocoaPods/search_index.json
然后再一次搜索AFNetworking
pod search AFNetworking
终端打印如下:
Creating search index for spec repo 'master'.. Done!
至此该问题解决！
