pod search AFN 如下错误

[!] CDN: trunk Repo update failed - 2 error(s):
CDN: trunk URL couldn‘t be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/4/a/2/afn/1.0.0/afn.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (Connection refused - connect(2) for "raw.githubusercontent.com" port 443)
CDN: trunk URL couldn‘t be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/4/a/2/afn/1.2.0/afn.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (Connection refused - connect(2) for "raw.githubusercontent.com" port 443)

解决办法

执行pod repo remove trunk移除trunk源，pod search就都正常了！

注意：podfile文件中一定要指定master源，因为现在默认是trunk源
