解決方案：
一、首先查看一下自己的ruby，看是不是?https://gems.ruby-china.com/
gem sources -l
二、如果不是?https://gems.ruby-china.com/?的源的話，就添加新源，卸載舊源；
gem sources --add?https://gems.ruby-china.com/?--remove?https://gems.ruby-china.org/
三、再次查看自己的ruby，看是否替換成功。如果顯示是https://gems.ruby-china.com/則說明替換成功。
gem sources -l
四、重新初始化安裝Pod。
sudo gem install -n /usr/local/bin cocoapods
五、成功之后查看一下版本有無,現(xiàn)在最新的是 1.5.3 版本。
pod --version
六、如果沒什么問題的話嗎，就cd到自己的工程目錄下進行更新第三方庫
pod install --verbose --no-repo-update
