Cocoapods 升级最新版本CDN异常问题（1.9.1）解决方案

Cocoapods 1.7.2 版本开始增加 CDN 支持但默认没有启用，
1.8 版本的发布舍弃了原始完整克隆的 Specs 仓库，改用 CDN 服务。

安装最新版本 Cocoapods 报错提示如下：

解决办法

1，首先要安装 Xcode 命令行工具
xcode-select --install

2，查看版本
pod --version

3，查看gem源
gem sources

如果不是源：https://gems.ruby-china.com ，使用以下方式增加新源：
添加源
gem sources -a https://gems.ruby-china.com

删除之前的源
gem sources --remove https://gems.ruby-china.org/

然后查看源：
gem sources

4，使用源安装CocoaPods库
git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master

如果特别慢，使用以下源安装CocoaPods库
git clone https://gitee.com/mirrors/CocoaPods-Specs.git ~/.cocoapods/repos/master

然后执行以下命令：
pod setup

使用CocoaPods:
打开podfile文件 指定旧方式下载。
// source 源地址
source ‘https://github.com/CocoaPods/Specs.git’

例如：

platform :ios, ‘9.0’

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

target '项目target名' do
	pod 'AFNetworking', '~> 3.1.0'
end

然后执行命令：
pod install

理论上讲：以上可以解决新版本1.9.1 CocoaPods安装异常的问题。

---

如果以上不能解决问题，可尝试卸载CocoaPods，重新安装指定版本的CocoaPods。（折腾啊）

卸载CocoaPods
sudo gem uninstall cocoapods （卸载当前的CocoaPods）

指定版本号安装CocoaPods
sudo gem install cocoapods -v 0.38.1 （安装0.38.1版本号的CocoaPods）

---

如果出现其他的问题：也可以尝试一下：
curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to storage.googleapis.com:443

移除代理
git config --global --unset http.proxy
git config --global --unset https.proxy
