在我的react原生项目中，我在尝试安装模块firebase/crashlytics后开始收到错误。

[!] CocoaPods could not find compatible versions for pod "FirebaseCore":
  In Podfile:
    FirebaseCore

    FirebaseStorageInternal was resolved to 9.6.0, which depends on
      FirebaseCore (~> 9.0)

    RNFBApp (from `../node_modules/@react-native-firebase/app`) was resolved to 16.4.3, which depends on
      Firebase/CoreOnly (= 10.1.0) was resolved to 10.1.0, which depends on
        FirebaseCore (= 10.1.0)

我尝试过：

sudo gem install cocoapods-clean
pod deintegrate
pod install
pod update
pod repo update && pod install --repo-update
yarn install

没有任何帮助。我想在我遇到问题之前，firebase/core版本是8。我如何更改10.1.0版本？这个pod是如何安装的，我在pod文件中没有看到它。
