[!] CDN: trunk Repo update failed - 27 error(s):

由于项目是用CocoaPods管理，CocoaPods 1.8将CDN切换为默认的spec repo源，并附带一些增强功能！CDN支持最初是在1.7版本中引入的，最终在1.7.2中完成。它旨在大大加快初始设置和依赖性分析。

目前项目使用pods的是1.8.4版本

zhoulangkejideiMac:iosAndVue linmac$ pod --version
1.8.4

使用pods出现

[!] CDN: trunk Repo update failed - 27 error(s):
CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/a/a/4/Masonry/0.0.2/Masonry.podspec.json, error: Failed to open TCP connection to raw.githubusercontent.com:443 (Connection refused - connect(2) for "raw.githubusercontent.com" port 443)

按照官方文档 podfile文件中添加source源：
source 'https://github.com/CocoaPods/Specs.git'
podfile文件中添加source源后，pod install和pod update可以正常操作，但是pod search有些库却不正常。

zhoulangkejideiMac:iosAndVue linmac$ pod search MBProgressHUD
[!] CDN: trunk Repo update failed - 10 error(s):

解决办法：

podfile文件中指定source源为master：
source 'https://github.com/CocoaPods/Specs.git'

2.执行pod repo remove trunk移除trunk源
执行完后，pod search就都正常了！

zhoulangkejideiMac:iosAndVue linmac$ pod search MBProgressHUD
-> MBProgressHUD (1.1.0)
   An iOS activity indicator view.
   pod 'MBProgressHUD', '~> 1.1.0'
   - Homepage: http://www.bukovinski.com
   - Source:   https://github.com/matej/MBProgressHUD.git
   - Versions: 1.1.0, 1.0.0, 0.9.2, 0.9.1, 0.9, 0.8, 0.7, 0.6, 0.5
   [edu-git-cocoapods-specs repo]

-> MBProgressHUD+Add (0.0.2)
   给UIView和UIViewController添加HUD扩展,以便使用.
   pod 'MBProgressHUD+Add', '~> 0.0.2'
   - Homepage: https://github.com/ONECATYU/MBProgressHUD-Add
   - Source:   https://github.com/ONECATYU/MBProgressHUD-Add.git
   - Versions: 0.0.2, 0.0.1 [edu-git-cocoapods-specs repo]

-> MBProgressHUD+BWMExtension (1.0.1)

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

source 'https://github.com/CocoaPods/Specs.git'
