iOS安装CocoaPods步骤:

CocoaPods官网：https://cocoapods.org/

$ sudo gem install cocoapods 一键安装
cocoaPods依赖Ruby,Gem， 检查下这两个是否安装好
$ ruby -v
$ gem -v
都显示版本说明安装成功
使用前需要初始化pod $ pod setup
此步骤遇到stucking情况，进度一直卡在下载mater不动
解决方法：

git clone github.com/CocoaPods/S… ~/.cocoapods/repos/master
pod setup

主要是下载cocoapods的库出现问题，可以手动下载也可以命令直接下载拷贝，之后再pod setup即可

uninstall cocoapods

First, determine which version(s) of Cocoapods you have installed by running this in Terminal:

gem list --local | grep cocoapods

You see output similar to this:

cocoapods (0.27.1, 0.20.2) cocoapods-core (0.27.1, 0.20.2) cocoapods-downloader (0.2.0, 0.1.2)

Here, I have two versions of Cocoapods installed.

To completely remove, issue the following commands:

gem uninstall cocoapods gem uninstall cocoapods-core gem uninstall cocoapods-downloader

If you have multiple versions installed, like I have, it will prompt you to choice a specific version or all. If you want to uninstall a specific version you can also use the -v switch as follows:

gem uninstall cocoapods -v 0.20.2 Running gem list --local | grep cocoapods again will confirm that Cocoapods has been removed.
