Ionic 找不到 android_sdk_root，无法在 phone 上构建应用程序

Question

当我在 vscode 终端提示 ionic cordova build android 时，过了一会儿它给了我：

Checking Java JDK and Android SDK versions
ANDROID_SDK_ROOT=undefined (recommended setting)
ANDROID_HOME=undefined (DEPRECATED)
Failed to find 'ANDROID_SDK_ROOT' environment variable. Try setting it manually.
Failed to find 'android' command in your 'PATH'. Try update your 'PATH' to include path to valid SDK directory.
[ERROR] An error occurred while running subprocess cordova.

        cordova.cmd build android exited with exit code 1.

        Re-running this command with the --verbose flag may provide more
        information.

我检查了我的路径，我认为没问题？

我能得到一些帮助吗？

我想在 phone 上测试我的应用程序。我已经在 Xamarin 上获得 phone 运行。

我在这台计算机上安装了 Android Studio，但从未在该用户上执行过。我应该打开它吗？ [1]: https://i.stack.imgur.com/BO5wx.png [2]: https://i.stack.imgur.com/qQ4VE.png
