flutter - 无法找到或加载主类 username\AppData\Local\Android\SDK\cmdline-tools\latest\bin\\

Question

当我输入颤振医生时，我面临以下错误。

[!] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
X Android license status unknown.
  Run `flutter doctor --android-licenses` to accept the SDK licenses.
  See https://flutter.dev/docs/get-started/install/windows#android-setup for more details.

当我跑步时flutter doctor --android-licenses，它再次给我一个错误说'

Error: Could not find or load main class username\AppData\Local\Android\SDK\cmdline-tools\latest\bin\\..

由于我是初学者，有人可以帮我详细解决这个问题吗？
