无法使用以下规范在 macOS 上构建项目

Flutter 2.2.2 • channel stable • https://github.com/flutter/flutter.git
Framework • revision d79295af24 (10 days ago) • 2021-06-11 08:56:01 -0700
Engine • revision 91c9fc8fe0

Answer 1

我不确定这个解决方案是否适用于其他人，但这对我有用

在这里https://github.com/AgoraIO-Community/Agora-Flutter-Quickstart/blob/master/pubspec.yaml#L21:L23

将 Agora RTC 引擎版本和权限处理程序更改为

  agora_rtc_engine: ^4.0.1
  permission_handler: ^6.0.1

然后执行以下操作

• 删除 ios/Podfile.lock
• 删除 Pods 文件夹
• cd ios > pod install or pod install --repo-update
• 删除 pubspec.lock
• 删除构建文件夹
• 运行flutter pub get

如果还是不行

rm -rf /YourUserPath/.pub-cache
rm -rf ~/Library/Developer/Xcode/DerivedData
rm ios/Podfile
rm ios/Podfile.lock
rm pubspec.lock
rm -rf ios/Pods
rm -rf ios/Runner.xcworkspace
flutter clean
flutter build ios
flutter clean
flutter run
