我最近更新了Android Studio，因为该项目没有运行。
flutter run -v
Gradle task assembleDebug failed with exit code -1

许可和所有问题都存在，然后我运行
flutter doctor --android-licenses
！错误
A newer version of the Android SDK is required. To update, run:
usersDirPath\AppData\Local\Android\Sdk\tools\bin\sdkmanager --update
然后我跑
sdkmanager --update
它显示
Warning: Unknown argument -v
Warning: Could not create settings

我尝试过的事情
将jdk版本更改为8 https://github.com/flutter/flutter/issues/31116#issuecomment-529807607
安装Android SDK 26.1.1 (obsolete)
https://github.com/flutter/flutter/issues/51670#issuecomment-593068819
甚至完全卸载了android studio并重新安装。
帮我解决此错误。
Android Studio版本3.6.2
修改
我以某种方式（重新安装）设法接受了所有许可证，但是错误仍然相同。
