Flutter Doctor 错误 未找到 Android sdkmanager 工具

我一直在围绕这个问题转来转go ，有那么多人有similar个问题要问我，但没有一个是相同的.我正试图让弗利特完全准备好，但无法解决其中一个问题.

当我运行Ffltter Doctor-v时，我得到以下输出:

如果我try 运行Ffltter Doctor--Android-License命令，我会得到:

未找到Android sdkmanager工具

没错，我的SDK文件夹中没有"工具"文件夹.我到底该怎么解决这个问题！我已经安装了所有的SDK工具，甚至NDK(不是Flitter收集的)我也try 过创建工具文件夹并复制sdkManager.来自build tools的bat(包括bin文件夹)，但这只是告诉我更新我的SDK管理器，当try 时就会失败.

看起来一切都正常，只是让我有点不舒服.

如有任何帮助，我们将不胜感激.
