[解決済み] Flutter。CocoaPodsのspecリポジトリは古すぎて依存関係を満たせない

質問

現在、私は firebase_core: ^0.5.0+1 と firebase_crashlytics: ^0.2.1+1 のパッケージを最新バージョンにすると、Androidでは問題なく動作するのですが、iOSでは動作せず、エラーが発生します。iOSのFlutterプロジェクトで最新のパッケージを使用してプロジェクトを実行するにはどうすればよいでしょうか？

また、私は pod repo update も試しましたが、まだうまくいきません。

このエラーは flutter run

    [!] CocoaPods could not find compatible versions for pod "GoogleDataTransport":

    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     * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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 `GoogleDataTransport` inside your development pod `firebase_crashlytics`.
       You should run `pod update GoogleDataTransport` to apply changes you've made.

どのように解決するのですか？

これはあなたにとってどんな意味があるのでしょうか？

さて、基本的にあなたのCocoaPodsのセットアップは は壊れそうです。 . Specs リポジトリのローカル コピーを手動で削除し、Specs リポジトリの新しいバージョンを再クローンする必要があります。

多くの解決策を適用した後、私はこのエラーを解決するのに成功した方法を見つけました。

ターミナルで次のコマンドを実行することで解決できます。

1. に移動します。 /ios フォルダに移動します。

2. 削除する Podfile.lock (YourPoject/ios/Podfile.lock)。

3. ここで、あなたは チップに従って行う必要があります。 ここでは、両方のチップに対応するようにしました。

   のために Intel chip ユーザ

   1. 実行 pod install --repo-update (flutterアプリのiOSディレクトリにcdしてください。）

   について M1 chip ユーザー

   1. ffiを先にインストールする（インストールされていない場合） 通常のターミナルでコマンドを使用する。 sudo arch -x86_64 gem install ffi 次に arch -x86_64 pod install --repo-update

4. 実行 flutter clean

5. 完了したら、Flutterアプリケーションを再構築します。 flutter run

P.S - もし、一回目の処理をすべて行ったが、それでも問題が解決されない場合は、次のコマンドを実行してください。 pod repo remove trunk ステップの後 2 .これを特定してくれた@drpaweloに感謝します。
