GeneratedPluginRegistrant.h:8:9:'Flutter/Flutter.h'文件未找到

当我在 GitHub Actions 中的 macOS Catalina 10.15.7 中使用此命令编译我的 flutter（2.0.1 版）项目时（今天我在本地 macOS 机器上发现了同样的问题并且挣扎了好几天）：

bundle exec fastlane beta

它显示此错误：

这个项目总是构建成功 util 我最近将它升级到 flutter 2.0.1。问题出在哪里，我应该怎么做才能解决这个问题？现在我正在使用 xcode 编译也显示此错误。我已经尝试删除Flutter.podspec：

rm ios/Flutter/Flutter.podspec
flutter clean

并在 XCode 12.4 中重建项目，仍然没有修复它。

这是我的颤振版本信息：
