当我尝试 运行 flutter doctor --android-licenses 时，出现了这个错误：

任何人都可以告诉我我的错误在哪里吗？
对我来说，flutter doctor --android-licenses 出于某种原因没有用。
唯一有效并解决问题的命令是：
(your android_sdk folder exact path)\tools\bin\sdkmanager --licenses
安装 android sdk 命令行工具来自
Android studio-> preferences-> appearance & Behaviors -> System Setting -> Android Sdk -> android sdk tools -> android Sdk Command line tools 让它检查和申请。
之后你可以运行你的命令。
