ios - 启动应用程序时出错 - Flutter - iOS

Question

我第一次在 iOS 应用程序上工作，有一个完整的 flutter 项目，它的 android 应用程序已经在 Play 商店中。问题是我无法在模拟器或物理设备 iPhone 6s 中运行该应用程序。在过去的三天里，我尝试了所有可能的解决方案，但到目前为止都没有奏效。
我在终端中尝试过的命令如以下答案之一所示:

flutter pub get
cd ios && pod update
flutter clean && flutter run

虽然，我已经尝试了其他各种命令/步骤来解决问题，例如 flutter upgrade但到目前为止没有任何帮助。
我得到的错误:

Answer 1

尝试执行此步骤
清除所有 pod 及其关系:
在终端:cd ios

flutter clean
rm -Rf Pods
rm -Rf .symlinks
rm -Rf Flutter/Flutter.framework
rm -Rf Flutter/Flutter.podspec
rm Podfile

然后

flutter run 

它将自动安装 pod(第一次运行可能需要一些时间，具体取决于您的依赖项)。
