我想在没有Android Studio的情况下安装Flutter。所以，我手动安装了Android SDK。当我运行“sdkmanager --licenses”时，结果是：

~$ sdkmanager --licenses
[=======================================] 100% Computing updates...             
All SDK package licenses accepted.

之后，我运行“Flutter医生-v”。结果：

$ flutter doctor -v

所以我运行这个命令flutter doctor --android-licenses。它说：

Android sdkmanager not found. Update to the latest Android SDK and ensure that
the cmdline-tools are installed to resolve this.

我已经安装了cmdline-tools，但为什么仍然得到这个错误？我已经观看或阅读了有关如何解决这个问题的教程，但他们都使用Android Studio，而不是像我一样手动安装.
想要解决“Android许可证状态未知”的问题，并在没有Android Studio的情况下将Flutter安装在我的PC上
