RubyGems是什么

RubyGems简称gem，是一个对Ruby组建进行打包的Ruby打包系统。

三、安装CocoaPods

安装

1、更新gem

2、查看Ruby的源

gem source -l

终端中：

https://gems.ruby-china.org/
https://ruby.taobao.org/

如果有淘宝的源，需要删除，因为taobao Gems源已停止维护，现由 ruby-china 提供镜像服务。

3、删除https://ruby.taobao.org/

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

4、设置ruby-china为Ruby的源

gem sources -a https://gems.ruby-china.org/

5、安装CocoaPods

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

pod setup

Mac OSX 10.11之前，用下面命令：

sudo gem install cocoapods

报错处理

如果报错

ERROR:  SSL verification error at depth 2: self signed certificate in certificate chain (19)
ERROR:  Root certificate is not trusted (/C=US/O=GeoTrust Inc./CN=GeoTrust Global CA)
ERROR:  SSL verification error at depth 2: self signed certificate in certificate chain (19)

ERROR:  While executing gem ... (OpenSSL::SSL::SSLError)
    hostname "gems.ruby-china.org" does not match the server certificate

用如下操作：

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

pod setup
