当我运行flutter doctor（MacOS索诺马）时，它告诉我安装了cocoapods：

[!] Xcode - develop for iOS and macOS (Xcode 15.0)
    ✗ CocoaPods installed but not working.
        You appear to have CocoaPods installed but it is not working.
        This can happen if the version of Ruby that CocoaPods was installed with is different from the one being used to invoke it.
        This can usually be fixed by re-installing CocoaPods.
      To re-install see https://guides.cocoapods.org/using/getting-started.html#installation for instructions.

但当我试图删除它：

george@mycomputer % sudo gem uninstall cocoapods
Gem 'cocoapods' is not installed
george@mycomputer % sudo gem uninstall -n /usr/local/bin cocoapods
Gem 'cocoapods' is not installed
george@mycomputer ~ % brew uninstall cocoapods
Error: Cask 'cocoapods' is not installed.

椰子还能在哪里/怎么样，以及如何去除它？
