cocoapod安装失败

安装 cocoapods报错，替换国内源：
ERROR:  Could not find a valid gem ‘cocoapods‘ (>= 0), here is why:
          Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/latest_specs.4.8.gz)
解决办法：换源地址
gem sources --remove http://ruby.taobao.org/ //移除原文件地址 
gem sources -a https://ruby.taobao.org/   //添加新文件地址
gem sources -l    //查看源文件地址是否正确
sudo gem install cocoapods    //更新
