无法运行“adb”，请检查您的 Android SDK 安装和 ANDROID_SDK_ROOT 环境变量：...\Android\Sdk\platform-tools\adb.exe

Question

当我启动项目时，弹出窗口显示“Flutter daemon terminate”，当启动 flutter 应用程序时，它显示“未找到连接的设备”对话框。 然后我运行flutter doctor -v医生发现问题：

Connected device (the doctor check crashed)
X Due to an error, the doctor check did not complete. If the error message below is not helpful, please let us know about this issue at https://github.com/flutter/flutter/issues.

我已经在用户变量和tools中将 SDK 路径设置为 ANDROID_SDK_TOOLS ，并在路径中设置platform-tools 。 并重新安装了platform-tools ，但没有解决问题。 如果有人能给我一个解决方案，我想不出解决方案，我将不胜感激。

以下日志显示在事件日志中：

12/2/2021
12:26 AM    'C:\Users\Pulsara\AppData\Local\Android\Sdk\platform- 
tools\adb.exe start-server' failed -- run manually if necessary

12:26 AM    'C:\Users\Pulsara\AppData\Local\Android\Sdk\platform-

12:26 AM    * daemon not running; starting now at tcp:5037

12:26 AM    * daemon started successfully

12:26 AM    Adb connection Error:An existing connection was forcibly 
closed by the remote host

12:26 AM    Cannot reach ADB server, attempting to reconnect.

我仍然无法解决问题。

问题出在防病毒程序中。 它拒绝访问在port 5037上启动 flutter 守护程序。 我只是从我的设备上卸载了防病毒程序。 然后它就像一个魅力。
