pod 出错备忘

pod install

#输出信息

查看 Ruby 版本：

$ ruby -v

ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin12.0]

rvm install 2.3.0

升级 Ruby 2.3 仍有问题，更新步骤：

1、 更新 gem ，国内需切换 gem source 

curl -L https://get.rvm.io | bash -s stable --autolibs=enabled --ruby --rails --trace

或 sudo gem update --system

• 切换 gem source 

$ gem sources --add https://ruby.taobao.org/ --remove https://rubygems.org/

$ gem sources -l
*** CURRENT SOURCES***

https://ruby.taobao.org

2、 安装 cocoapods 

$ sudo gem install cocoapods
 $ pod setup

和安装过程是一样的，再次查看 pod 版本：

$ pod --version
.39.0
