Question

这是我要使用VS Code构建Flutter应用程序的方法。当我运行以下命令flutter build apk

FAILURE: Build failed with an exception.

* Where:
Build file 'F:\year-03\SEM2\events\GSOC\LabelLab\labellab_mobile\android\build.gradle' line: 27

* What went wrong:
A problem occurred evaluating root project 'android'.
> 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   

     Using Android SDK: C:\Users\Mr.Semicolon\AppData\Local\Android\sdk

要了解确切的解决方案，我将介绍在VS Code IDE中设置Flutter所遵循的所有步骤。
1.从https://flutter.dev
下载Flutter Windows SDK 2.将文件解压缩到C驱动器
3.转到文件路径C:\flutter\bin并设置环境变量。
4.在VS Code IDE中，安装Flutter和Dart扩展。
5.使用flutter build apk

运行该应用程序

编辑： flutter doctor输出，

Answer 1

此错误是由于缺乏许可协议所致。

打开终端。
flutter doctor --android-licenses
按y接受每个许可证。

Answer 2

在某些计算机上，您需要以管理员身份打开命令提示符。因此，您可以尝试以下步骤并检查

以管理员身份执行命令提示符。
运行命令flutter doctor --android-licenses并接受所有命令。通过按 Y 来获得许可。
运行命令flutter doctor -v来检查问题是否仍然存在；
以常规用户身份登录，然后尝试flutter doctor -v以确保一切正常。

如果仍然给您同样的问题，请访问flutter文件夹并打开名为 flutter_console.bat 的文件，然后键入此命令flutter doctor --android-licenses。

VS代码：由于某些许可证未被接受，因此无法安装以下Android SDK软件包
