【问题描述】：

我正在做一个移动实习和学习颤振，我已经将我的机器配置为在我的手机上运行和构建我的应用程序 apk，昨天我将我的 HDD 切换到 SSD，然后我们再次下载并安装所有东西，现在什么时候我尝试运行我的应用，我得到了这个：FAILURE: Build completed with 2 failures. 这就是两次失败：

BUILD FAILED in 4s

另外，当我运行颤振医生时，我遇到了这个问题：

[!] Android toolchain - develop for Android devices (Android SDK version 31.0.0)
    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.

但是当我尝试运行 flutter doctor --android-licenses 时，我收到了这个日志错误：

【问题讨论】：

确实尝试运行flutter doctor --android-licenses

是的，我试过了，但我也遇到了另一个错误，日志在我的问题的最后

【参考方案1】：

我解决它只是卸载并重新安装 Android Studio 和 Flutter，如果您遇到此问题，可能您的 Android Studio 已损坏。
