首先我的Mac系统是OS X EI

先安装cocoa pods

1.更换环境

gem sources --remove https://rubygems.org/

gem sources -a https://ruby.taobao.org/

2.输入

gem sources -l

显示*** CURRENT SOURCES ***

https://ruby.taobao.org/

3.mac OS X EI   要输入sudo gem install -n /usr/local/bin cocoapods

4.pod setup出现如下错误

Setting up CocoaPods master repo

[!] /usr/bin/git clone https://github.com/CocoaPods/Specs.git master

Cloning into 'master'...

error: RPC failed; curl 56 SSLRead() return error -36

fatal: The remote end hung up unexpectedly

fatal: early EOF

fatal: index-pack failed

这时要输入sudo xcode-select --switch /Applications/Xcode.app

之后再输入pod setup

这时会显示

Setting up CocoaPods master repo

Setup completed

开始使用cocoa pods

以iCarousel为例

1.查找iCarousel的版本pod search iCarousel

2.新建工程，cd到自己的工程里cd /Users/shenlulu/Documents/cocoapodsTest（输完cd后找到文件直接拖过来）

3.vim Podfile

在Pod file里面输入

platform :ios

target "cocoapodsTest" do

pod 'iCarousel', '~> 1.8.2'

end

保存退出

4.pod install

显示如下
