安装软件包后在 iOS 模拟器上运行时，我什至尝试过pod update Firebase/Firestore仍然出现以下错误。cloud_firestore

甚至我也尝试过多次删除 Podfile.lockflutter clean然后flutter run.

注意：

  1. Flutter 版本：Flutter 2.0.2

  2. 飞镖 2.12.1

    无法构建 iOS 应用 Xcode 构建的错误输出：↳ ** BUILD FAILED **

你需要删除 podfile.lock

然后你需要从 XCode 运行 iOS 文件夹来为你的项目加载资产

转到ios文件夹并执行pod install，如果它不存在pod init则执行pod install

请尝试 Xcode -> 产品 -> 运行

首先删除 podfile.lock 并按照以下步骤操作；

flutter clean
flutter pub get
cd ios
pod install
flutter run

如果不起作用，请检查您的颤振通道并将其更改为 beta。

flutter pub upgrade
flutter channel beta
flutter clean
cd ios
pod install
flutter run

您也可以在下面切换回稳定打字；

flutter channel beta

这解决了我的问题GitHub 问题

尝试在您的 ios 目录中运行这些命令：

rm -rf Pods
rm -rf Podfile.lock
rm -rf ~/.pub-cache/hosted/pub.dartlang.org/
pod cache clean --all
flutter clean
flutter pub get
pod repo update
pod install
