pod search 搜索类库失败

pod search AFNetworking 搜索类库失败 可执行以下命令解决：

rm ~/Library/Caches/CocoaPods/search_index.json
pod search AFNetworking

如果还是报错如下：

[!] CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/6/2/b/Lwt_Networking/1.0.1/Lwt_Networking.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (getaddrinfo: nodename nor servname provided, or not known)

执行pod repo remove trunk移除trunk源，然后再pod search AFNetworking 就正常了！
