Dart/Flutter | CocoaPods could not find compatible versions for pod "Firebase/CoreOnly" 에러 해결하기

Flutter 프로젝트에서 Firebase Cloud Message를 사용하기 위해 Firebase 라이브러리를 사용중이다. Flutter 업그레이드한 후 ios나 macos에서 빌드할 때 오류가 발생하여 ios 또는 macos 디렉토리에서 pod install 명령을 실행했으나 아래와 같은 결과를 확인하였다.

$ pod install

[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
  In snapshot (Podfile.lock):
    Firebase/CoreOnly (= 11.8.1, ~> 11.8.0)

  In Podfile:
    firebase_core (from `Flutter/ephemeral/.symlinks/plugins/firebase_core/macos`) was resolved to 3.13.0, which depends on
      Firebase/CoreOnly (~> 11.10.0)

Specs satisfying the `Firebase/CoreOnly (= 11.8.1, ~> 11.8.0), Firebase/CoreOnly (~> 11.10.0)` dependency were found, but they required a higher minimum deployment target.

None of your spec sources contain a spec satisfying the dependency: `Firebase/CoreOnly (~> 11.10.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

 

You have either 항목에 설명되어 있는데, $ pod repo update 또는 $ pod install --repo-update를 실행하면 된다고 한다. 그래서 지체없이 $ pod install --repo-update를 실행했다.

$ pod install --repo-update
