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 db.exe

Question

当我启动项目时，弹出窗口显示“Flutter 守护进程终止”，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.

我已经在用户变量中将 SDK 路径设置为 ANDROID_SDK_TOOLS，并在路径中设置了

tools

和

platform-tools

。并重新安装了

platform-tools

，但没有解决问题。我无法找到解决方案，如果有人能给我一个解决方案，我将非常感激。

事件日志中显示以下日志：

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- 
tools\adb.exe start-server' failed -- run manually if necessary

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.

我还是没能解决问题。

Answer 1

未执行我在问题中提到的任何步骤后尝试此步骤。

问题出在防病毒程序中。它拒绝访问在

port 5037

上启动 flutter 守护进程。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。

运行 flutter config --android-studio-dir="C:\Program Files\Android\Android Studio" 当找不到 AndroidStudio 的路径时会出现此问题。确保您使用 AndroidStudio 的正确路径。
