这是因为升级了macOS 的系统,导致cocoapods不能使用.
当你的Mac系统升级为 high sierra 的时候，别忘记更新cocoapods.

执行命令为：

$ sudo gem update --system
$ sudo gem install cocoapods -n/usr/local/bin

以上基本问题可以解决了.

再次更新,会出现下面界面,说明成功:

参考指令

1、更新gem：sudo gem update --system

2、删除gem源：gem sources --remove [https://ruby.taobao.org/](https://ruby.taobao.org/)

3、修改gem源：gem sources -a [https://gems.ruby-china.org](https://gems.ruby-china.org/)

4、查看gem源是否是最新的：gem sources -l

5、升级cocoapods：sudo gem install -n/usr/local/bin cocoapods --pre

6、查看升级后的cocoapods版本：pod --version
