[Flutter] iOS 시뮬레이터 Run 중 발생 오류 - Error output from CocoaPods : [!] The version of CocoaPods used to generate the lockfile (1.11.3) is higher than the version of the current executable (1.11.2).

기존에 개발자가 간략하게 플러터 프로젝트를 생성하고 튜토리얼 화면을 만들어 놓았는데, 이를 확인하기 위해 내 노트북에서 플러터 프로젝트를 시뮬레이터로 돌리는 것부터 에러가 발생했다.

 

Error output from CocoaPods:

[!] The version of CocoaPods used to generate the lockfile (1.11.3) is higher than the version of the current executable (1.11.2). Incompatibility issues may arise.

[!] Automatically assigning platform `iOS` with version `11.0` on target `Runner` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform`.

Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies. To update the CocoaPods specs, run: pod repo update

Error running pod install

Error launching application on iPhone 12.

 

기존에 개발자가 사용한 버전이 낮아서 발생하는 문제다.

해결방법

 

아래 파일을 지우고

ios/podfile.lock

 

$pod install 실행

 

그러나 또다른 오류 발생

 

Analyzing dependencies

firebase_analytics: Using Firebase SDK version '10.3.0' defined in 'firebase_core'

firebase_core: Using Firebase SDK version '10.3.0' defined in 'firebase_core'

Warning: firebase_app_id_file.json file does not exist. This may cause issues in upload-symbols. If this error is unexpected, try running flutterfire configure again.

firebase_crashlytics: Using Firebase SDK version '10.3.0' defined in 'firebase_core'

firebase_dynamic_links: Using Firebase SDK version '10.3.0' defined in 'firebase_core'

firebase_messaging: Using Firebase SDK version '10.3.0' defined in 'firebase_core'

[!] CocoaPods could not find compatible versions for pod "Firebase/Auth":

  In Podfile:

    firebase_auth (from `.symlinks/plugins/firebase_auth/ios`) was resolved to 4.2.3, which depends on

      Firebase/Auth (= 10.3.0)

 

None of your spec sources contain a spec satisfying the dependency: `Firebase/Auth (= 10.3.0)`.

 

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.

 

 

- iOS 11 버전을 Podfile에 적어야 해결된다 하여 보았지만 이미 적혀있어서 이것이 원인은 아닌 것으로 보인다.

 

M2 버전의 문제일 수도 있는데..
