在执行flutter运行时，出现了错误。这个错误与pod文件有关。有人知道如何解决吗？

我尝试了pod repo update，但它不起作用。我在Mac上运行。我尝试重新安装cocoapods，但也没有帮助。我该如何解决这个问题？我已经困在这个问题上一天了。这是它报错的内容：

错误：CocoaPods的规范存储库太过过时，无法满足依赖关系。

要更新CocoaPods规范，请运行：

pod repo update

运行pod install时出错

在iPhone 13上启动应用程序时出错。

[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
  In snapshot (Podfile.lock):
    Firebase/CoreOnly (= 8.7.0)
  In Podfile:
    firebase_core (from `.symlinks/plugins/firebase_core/ios`) was resolved to 1.10.6, which depends on
      Firebase/CoreOnly (= 8.9.0)
You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * changed the constraints of dependency `Firebase/CoreOnly` inside your development pod `firebase_core`.
   You should run `pod update Firebase/CoreOnly` to apply changes you've made.
