我不能接受 Android SDK 許可證

Question

我剛剛在我的 MacBook（Big Sur 11.4）上安裝了 Flutter（2.2.1）。 這是我在終端中運行flutter doctor時的結果。

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 2.2.1, on macOS 11.4 20F71 darwin-x64, locale
    en-GB)
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.3)
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/macos#android-setup for
      more details.
[✗] Xcode - develop for iOS and macOS
    ✗ Xcode installation is incomplete; a full installation is necessary for iOS
      development.
      Download at: https://developer.apple.com/xcode/download/
      Or install Xcode via the App Store.
      Once installed, run:
        sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
        sudo xcodebuild -runFirstLaunch
    ✗ CocoaPods not installed.
        CocoaPods is used to retrieve the iOS and macOS platform side's plugin
        code that responds to your plugin usage on the Dart side.
        Without CocoaPods, plugins will not work on iOS or macOS.
        For more info, see https://flutter.dev/platform-plugins
      To install see
      https://guides.cocoapods.org/using/getting-started.html#installation for
      instructions.

當我運行flutter doctor --android-licenses這是給出的錯誤

我還安裝了 Java JDK 16.0.1，沒有任何改變。 當我嘗試在 Android Studio 上運行應用程序時出現錯誤

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Failed to install the following Android SDK packages as some licences have not been accepted.
     build-tools;29.0.2 Android SDK Build-Tools 29.0.2
  To build this project, accept the SDK license agreements and install the missing components using the Android Studio SDK Manager.
  Alternatively, to transfer the license agreements from one workstation to another, see http://d.android.com/r/studio-ui/export-licenses.html

  Using Android SDK: /Users/vladponcea/Library/Android/sdk

我到處搜索，但找不到解決方案。

剛剛獲得 SDK 管理器 > SDK 工具 > 安裝命令行工具，然后運行許可證命令。

單擊該框圖標，它將帶您到 SDK 管理器
