Answer 1

可能错误出在某些 XCode 项目文件上，请尝试：

1. 备份您的项目。

2. 运行 这个命令

   扑干净&&\ rm ios/Podfile ios/Podfile.lock pubspec.lock && \ rm -rf ios/Pods ios/Runner.xcworkspace && \ 颤动 运行

Answer 2

由于存在缓存，这通常是依赖项解析问题。如果您无法为 iOS 构建，无论插件版本如何，请执行以下步骤。

注意：建议您时不时地执行此操作，它还会清除您机器上大量使用过的 space。

1. 在 project/ios 文件夹中，运行 pod deintegrate && rm Podfile.lock && pod install
2. 在您的项目文件夹中，运行 flutter clean
3. 通过 运行ning rm -rf ~/Library/Developer/Xcode/DerivedData
清除 Xcode 派生数据
4. 使用 Xcode 打开项目并通过 Cmd + Shift + K
进行清理
5. 使用 flutter build ios 命令构建。

在使用 m1 芯片的 mac 中，我无法在模拟器中 运行 我的项目，而是我不得不使用物理 iPhone 连接并且它没有显示错误， 运行没问题。
