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 上运行并且它可以运行！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......

\n

这是我的 pubspec.yaml （firebase 依赖项）：

\n

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

Answer 1

删除ios/Pods文件夹。

删除Podfile和Podfile.lock

删除pubspec.lock

打开终端并依次运行这些命令

cd ios
pod cache clean --all
flutter clean
flutter pub get
pod install

Answer 2

这个错误来自 .pub-cache，所以只需 flutter clean，如果错误仍然存​​在，请删除所有 .pub-cache

从 pubspec.yaml 中的依赖项中删除包，运行 flutter packages get。然后再次将包添加到依赖项中并运行 flutter packages get。这个过程已经为我解决了过去的问题。
