一.更改镜像:

1.查看当前的镜像,在终端输入：gem sources -l

结果：

*** CURRENT SOURCES ***

https://rubygems.org/

2.删除当前镜像,在终端输入：gem sources --remove https://rubygems.org/

结果:https://rubygems.org/ removed from sources

3.添加阿里镜像,在终端输入:gem sources -a http://rubygems-china.oss.aliyuncs.com

4.查看当前的镜像,在终端输入:gem sources -l

结果:

*** CURRENT SOURCES ***

http://rubygems-china.oss.aliyuncs.com

表示更换成功。

二.安装Cocoapods:

1.终端输入:sudo gem install cocoa pods

如果出现以下错误：

“Error installing cocoapods:  activesupport requires Ruby version >= 2.2.2.”

则要更新ruby步骤如下(都是在终端输入):

1.curl -L get.rvm.io | bash -s stable

结果：“In case of problems: https://rvm.io/helpandhttps://twitter.com/rvm_io”

2.source ~/.bashrc

3.source ~/.bash_profile

4.rvm -v

结果：“rvm 1.27.0 (latest) by Wayne E. Seguin, Michal Papis[https://rvm.io/]”

5.ruby -v

6.查看当前所有的版本: rvm list known

7.升级到2.2.2版本: rvm install 2.2.2

8.sudo gem update --system

9.sudo gem install cocoa pods

结果：“........ 73 gems installed”

表示安装成功。

三.下载Cocoapods依赖包

1.pod repo remove master

2.git clone https://git.coding.net/CocoaPods/Specs.git ~/.cocoapods/repos/master

3.pod repo update

四.使用Cocoapods

1.终端中输入:cd空格把项目拖入空格后面

如：MacBook-Pro:~ mac$ cd /Users/mac/Desktop/test

2.pod init

3.编写Podfile文件

如添加'AFNetworking'和‘SDWebImage’框架：

platform :ios, '9.0'

target 'test' do

pod 'AFNetworking'

pod 'SDWebImage'

end

4.pod install

结果："Pod installation complete! There are 2 dependencies from the Podfile and 2 total pods installed."

恭喜你可以正常使用了！
