ruby - XCODE 未安装 pod

Question

我正在尝试在我的项目中安装 pod 并收到错误

GoogleAppMeasurement需要 CocoaPods 版本>= 1.10.2，您当前的版本不满足，1.10.1.

我尝试使用 brew，它给了我这个错误：

The following directories are not writable by your user:
/usr/local/share/zsh
/usr/local/share/zsh/site-functions

You should change the ownership of these directories to your user.
  sudo chown -R $(whoami) /usr/local/share/zsh /usr/local/share/zsh/site-functions

And make sure that your user has write permission.
  chmod u+w /usr/local/share/zsh /usr/local/share/zsh/site-functions

有没有人对此有解决方案，我卡在里面很长时间了？
