Cordova构建(Android SDK平台26,Android SDK构建工具26.0.2)

我正在尝试使用cordova构建APK。 我从做以下事情开始:

1) sudo npm install -g cordova

2) cordova create app com.example.hello app

3) cordova platform add android

然后我使用:

cordova requirements

这将产生以下输出: 检测到Android Studio项目

Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: not installed 
android: Command failed with exit code ENOENT
Gradle: installed /usr/share/gradle/bin/gradle
(node:27773) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Some of requirements check failed

最后,我使用:

cordova build

其结果是:

* What went wrong:
A problem occurred configuring project ':CordovaLib'.
> You have not accepted the license agreements of the following SDK components:
  [Android SDK Platform 26, Android SDK Build-Tools 26.0.2].
  Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager.
  Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

我完全迷路了。任何帮助都将不胜感激!
