'cloud_firestore' 的 Flutter pod 安装错误

Question

我有一个带有 M1 芯片的 Mac。当我尝试使用 'cloud_firestore' 包调试 flutter 项目时，出现以下错误：

Error running pod install

我试过：

1- 转到 Podfile 并将“platform :ios, '8.0'” 更改为 9.0 和 10.0

2- flutter clean > flutter pub get

3- 我删除了 pod 和运行 pod install

4- 还有运行这个命令：

arch -x86_64 pod update

arch -x86_64 pod install --repo-update

但仍然出现同样的错误。任何帮助如何解决这个问题？

Answer 1

我解决了这个问题。

问题出在 'main.dart'。我从这个更改了 'main' 函数：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

对此：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  runApp(MyApp());
}

所以，我认为 Firebase.initializeApp() 上的选项参数现在是 必需的 。使用 FlutterFire CLI 添加选项解决了我的问题。另外，这里有关于此的文档： https://firebase.flutter.dev/docs/cli

Answer 2

我找到了另一个适合我的解决方案。我认为问题源于默认的 cocoapods 安装，如 cocoapods 首页上的指示，M1 与其 FFI（外部函数接口）不兼容。

改为通过自制软件安装 cocoapods，确保您获得与 Apple Silicon 兼容的版本。

These instructions 对我有用。

但它归结为 uninstalling cocoapods 并通过自制软件重新安装：

brew 安装 cocoapods
