Cocoapods pod install报错

[!] CDN: trunk Repo update failed - 32 error(s):
CDN: trunk URL couldn't be downloaded: https://raw.githubusercontent.com/CocoaPods/Specs/master/Specs/8/5/c/mob_sharesdk/0.0.1/mob_sharesdk.podspec.json Response: Couldn't connect to server

解决办法，在podfile里面添加：

source ‘https://github.com/CocoaPods/Specs.git’
target 'Runner' do

但是由于网络不好一直会卡在Cloning spec repo cocoapods from https://github.com/CocoaPods/Specs.git

解决办法：
1、直接去https://github.com/CocoaPods/Specs下载
2、下载完成后，修改下载下来文件夹的名字为master
3、commond+G打开路径~/.cocoapods/repos，替换里边的master文件夹
4、打开终端
5、终端输入命令： cd master文件的路径
6、终端输入命令：git init
7、终端输入命令：git remote add origin https://github.com/CocoaPods/Specs.git
8、终端输入命令：pod repo，如果成功出现入下图所示：
