Flutter 无法编译 iOS pod 错误

Question

为 iOS 编译工作了一段时间，我添加了一些依赖项并切换到我的 android emu，现在它无法为 iOS 编译。

我尝试创建一个新项目并在 iOS 上运行它，但我不断收到相同的错误。

公共规范：

dependencies:
  flutter:
    sdk: flutter


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^1.0.2
  google_maps_flutter: ^2.0.11
  flutter_map: any # or the latest version on Pub
  location: ^4.3.0

错误：

您是否尝试卸载然后安装cocoapods？

sudo gem uninstall cocoapods
brew install cocoapods
