在执行完 pod install –repo-update 后，得到一下错误:
[!] cdn: trunk Repo update failed - 13 error(s): CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/1/9/6/PayPalCommerce/2.0.0-beta/PayPalCommerce.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/1/9/6/PayPalCommerce/2.0.0/PayPalCommerce.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/1/9/6/PayPalCommerce/2.1.0/PayPalCommerce.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/3/3/d/PaymentKit/1.2/PaymentKit.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/6/8/c/StripeDashboardUI/0.1/StripeDashboardUI.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/6/8/c/StripeDashboardUI/0.2/StripeDashboardUI.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/6/8/c/StripeDashboardUI/0.3/StripeDashboardUI.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/7/4/0/CaamDauCompatible/1.2.0/CaamDauCompatible.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/8/0/f/SwiftyRefresher/0.1.0/SwiftyRefresher.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/c/9/1/acceptSDK/1.6.214/acceptSDK.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/c/9/1/acceptSDK/1.6.215/acceptSDK.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/c/9/1/acceptSDK/1.6.216/acceptSDK.podspec.json Response: Couldn't connect to server CDN: trunk URL couldn't be downloaded: https://cdn.jsdelivr.net/cocoa/Specs/c/9/1/acceptSDK/1.6.217/acceptSDK.podspec.json Response: Couldn't connect to server解决方法
前往文件夹：/etc/hosts， 在host里面添加：199.232.4.133 raw.githubusercontent.com 即可
先执行 pod repo remove trunk 然后再执行 pod install即可
pod中在target之前一行，增加
source 'https://github.com/CocoaPods/Specs.git' 即可
