flutter doctor --android-licenses 不起作用

Question

当我运行 flutter doctor 我注意到许可证状态未知。

[√] Flutter (Channel stable, v1.0.0, on Microsoft Windows [Version 10.0.17763.253], locale en-US)
[!] Android toolchain - develop for Android devices (Android SDK 28.0.3)
    X Android license status unknown.
[√] Android Studio (version 3.3)
[√] IntelliJ IDEA Ultimate Edition (version 2018.3)
[!] VS Code (version 1.30.2)
[!] Connected device
    ! No devices available

! Doctor found issues in 3 categories.

我发现为了解决许可证问题，我需要运行这个命令 flutter doctor --android-licenses。当我运行出现以下错误时：

The system cannot find the path specified.
The system cannot find the path specified.
The system cannot find the path specified.
A newer version of the Android SDK is required. To update, run:
C:\Users\myusername\AppData\Local\Android\sdk\tools\bin\sdkmanager --update

然后我尝试运行ning C:\Users\myusername\AppData\Local\Android\sdk\tools\bin\sdkmanager --update 我收到以下错误：

'E\AppData\Local\Android\Sdk\tools\bin\' is not recognized as an internal or external command,
operable program or batch file.
Error: Could not find or load main class com.android.sdklib.tool.sdkmanager.SdkManagerCli

我在网上到处找，找不到任何答案。我是新手，不知道如何解决这个问题。任何帮助都将非常感谢！

打开命令提示符进入AndroidSDK目录，然后执行上面的命令。

sdkmanager --update

Answer 2

在 Android Studio 中，您应该检查以确保安装了 Android SDK 命令行工具。添加这个解决了我在 Flutter 中的问题。
