Flutter iOS：如何修复“无法构建模块`firebase_core`”？

Question

我有一个颤振项目。首先，它必须在 android 及其工作上工作！一切都很酷。是时候让它在 iOS 上运行了，但是当我尝试在 iOS 模拟器上启动项目时出现以下错误：

遗憾的是，我没有找到任何可行的解决方案...

这是我的 pubspec.yaml（firebase 依赖项）：

  firebase_performance: ^0.7.0+7
  firebase_crashlytics: ^2.1.1
  firebase_core: any
  firebase_messaging: ^10.0.6
  flutter_local_notifications: ^8.1.1+2

Answer 1

这个错误来自 .pub-cache，所以只要清理干净，如果错误仍然存​​在，则删除所有 .pub-cache

从 pubspec.yaml 中的依赖项中删除包，运行 flutter 包得到。然后再次将包添加到依赖项中 运行flutter packages get。这个过程已经解决了这个问题 过去的我。

颤抖干净

然后发布获取

Answer 2

在 pubspec.yaml 添加 firebase_core:any 。然后运行flutter clean，flutter pub get。然后从终端 cd ios 中的项目根目录导航到 iOS 文件夹。然后运行pod install。现在运行flutter run，它应该会按预期工作。

Answer 3

对我有用的是使用 Firestore iOS SDK 的预编译版本，因为在编译过程中出现了问题。请参阅https://firebase.flutter.dev/docs/overview/#initializing-flutterfire 上的“改进 iOS 构建时间”部分

1. 从您的 podfile（例如 pod 'Firebase/Analytics'）。
2. 将预编译的 pod 添加到您的 podfile（参见上面的链接）。

我已将pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.7.0' 添加到 podfile 中的 runner 目标（这是旧版本，因为新版本也出现了一些错误）。

结果在您的 podfile 中如下所示：

target 'Runner' do
  use_frameworks!
  use_modular_headers!
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '8.7.0'
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end```
