在android中部署Ionic 4应用程序抱怨android SDK许可证未被接受

我正在尝试在android平台上部署一个ionic应用程序。在构建时，我得到以下错误

 BUILD FAILED in 1s
Error: /Users/sajimathew/personal/sajiideas/dosanddonts/frontend/platforms/android/gradlew: Command failed with exit code 1 Error output:
FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Failed to install the following Android SDK packages as some licences have not been accepted.
     build-tools;28.0.3 Android SDK Build-Tools 28.0.3
     platforms;android-28 Android SDK Platform 28
  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

我试过了

yes| ~/Library/Android/sdk/tools/bin/sdkmanager --licenses
yes| ~/Library/Android/sdk/tools/bin/sdkmanager --update

yes| ~/Library/Android/sdk/tools/bin/sdkmanager "build-tools;28.0.3"
yes| ~/Library/Android/sdk/tools/bin/sdkmanager "platforms;android-28"

这些都没有解决这个问题。有什么想法吗？

首先

转到文件-->设置-->系统设置-->Android SDK

导航到

sdk/tools/bin

运行

sdkmanager

./sdkmanager --licenses
