第一步:sudo gem update --system

如果是最新版的会出现Latest version currently installed. Aborting.

如果不是会出现

------------------------------------------------------------------------------

RubyGems installed the following executables:

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/gem

Ruby Interactive (ri) documentation was installed. ri is kind of like man 

pages for ruby libraries. You may access it like this:

  ri Classname

  ri Classname.class_method

  ri Classname#instance_method

If you do not wish to install this documentation in the future, use the

--no-document flag, or set it as the default in your ~/.gemrc file. See

'gem help env' for details.

RubyGems system software updated

第二步：移除旧的ruby

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

成功后会出现source https://rubygems.org/ not present in cache

第三步:安装新的

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

成功后会出现https://ruby.taobao.org/ added to sources

第四步：查看gem sources -l

成功后会出现

*** CURRENT SOURCES ***

https://ruby.taobao.org/

第五步:安装

sudo gem install cocoapods

失败的出现结果

第六步:查看pod setup

成功后会出现如下Setting up CocoaPods master repo

稍等几分钟会出现如下结果

Setup completed

第七步:开始使用,新建一个项目并且跳转到该项目

cd /Users/lihuan/desktop/TestPods

之后输入vim Podfile

然后键盘输入i 

进入编辑模式:例如下

platform:ios,'7.0'

pod 'MBProgressHUD','~>0.8'

platform:ios,'7.0'

pod 'AFNetworking','~>2.5'

然后输入esc :wq保存退出即可

然后pod install

成功出线如下结果

Installing AFNetworking (2.6.3)

完事

注意：

1.安装采用taobao的

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

2.出现这个错误时候解决方案

While executing gem ... (Errno::EPERM)     Operation not permitted - /usr/bin/fuzzy_match

解决：

sudo gem install -n /usr/local/bin cocoapods

3.在pod setup后出现这种情况

Setting up CocoaPods master repo

等待下载
