1.移除现有Ruby默认源

$gem sources –remove https://rubygems.org/

2.使用新的源

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

3.验证新源是否替换成功

$gem sources -l

4.安装CocoaPods

(1) $sudo gem install cocoapods 备注：苹果系统升级 OS X EL Capitan 后改为$ sudo gem install -n /usr/local/bin cocoapods

(2)  $pod setup

5.更新gem

$sudo gem update –system

错误1：

Error fetchinghttp://ruby.taobao.org/:

bad response Not Found 404 (http://ruby.taobao.org/specs.4.8.gz)

解决方案：把安装流程中 $gem sources -a http://ruby.taobao.org/ ---改为---->$ gem sources -a https://ruby.taobao.org/

错误2：

ERROR: While executing gem … (Errno::EPERM)

Operation not permitted - /usr/bin/pod

解决方案：苹果系统升级OS X EL Capitan后会出现的插件错误，将安装流程 4.安装CocoaPods 的 (1)sudo gem install cocoapods ——>改为sudo gem install -n /usr/local/bin cocoapods

错误3：

[!] Unable to satisfy the following requirements: - AVOSCloud (~> 3.1.6.3) required by Podfile

Specs satisfying the AVOSCloud (~> 3.1.6.3) dependency were found, but they required a higher minimum deployment target.

解决方案：安装流程：Podfile文件中 platform:ios, ‘6.0’ 后边的 6.0 是平台版本号，一定要加上
错误4：activesupport requires Ruby version >= 2.2.2.ruby运行环境版本过低，升级ruby版本即可
RVM:Ruby Version Manager,Ruby版本管理器，包括Ruby的版本管理和Gem库管理(gems)

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

测试是否安装正常

$ source ~/.bashrc

$ source ~/.bash_profile

查看当前rvm版本

$ rvm -v

用RVM升级Ruby

查看当前ruby版本

ruby -v

列出可更新的版本列表

$ rvm list known

安装ruby 2.3.0
