颤振医生 --android-licenses 不起作用 [英] flutter doctor --android-licenses does not work

问题描述

当我运行 flutter doctor 时，我注意到许可证状态未知.

when I run flutter doctor I noticed license status is unknown.

[√] 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，我需要运行这个命令 flutter doctor --android-licenses.当我运行时，我收到以下错误:

I found that in order to resolve the license I need to run this command flutter doctor --android-licenses. when I run that I get the following error:

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A newer version of the Android SDK is required.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 C:\Users\myusername\AppData\Local\Android\sdk\tools\bin\sdkmanager --update 我收到以下错误:

So I then tried running C:\Users\myusername\AppData\Local\Android\sdk\tools\bin\sdkmanager --update I received the below error:

'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.我是颤振的新手，不知道如何解决这个问题.任何帮助都会非常感谢！

I looked everywhere online and could not find any answer. I am new to flutter and do not know how to resolve this problem. Any help would be great thanks!
