【问题描述】：

我正在尝试使用 uiautomatorviewer 来捕获我通过 USB 连接的 Android 设备。我已卸载 Android SDK 并重新安装。我对安装或连接等 adb 命令没有任何问题。如下所示，我可以看到带有 adb devices 命令的设备，并且在使用 adb version 命令时可以看到 adb 版本。问题是当我启动 uiautomatorviewer 我遇到无法检测 adb 版本，adb 输出：此时没有其他任何反应，程序也没有连接到我的设备。

PS C:\Windows\system32> adb devices
List of devices attached
a2738481        device

PS C:\Windows\system32> adb version
Android Debug Bridge version 1.0.41
Version 30.0.3-6597393
Installed as C:\android-sdk\platform-tools\adb.exe
PS C:\Windows\system32> uiautomatorviewer
03:55:06 E/adb: Unable to detect adb version, adb output:
Terminate batch job (Y/N)? y
PS C:\Windows\system32>

认为我的 uiautomatorviewer.bat 文件可能有问题

请注意，当我在 C:\android-sdk\tools 中运行 monitor.bat 时，它可以正常工作

【解决方案1】：

-我删除并重新安装了 Android SDK -我尝试过以前的旧 SDK - 尝试过 powershell 和命令提示符 -删除和添加环境变量的路径最终解决我的问题的唯一一件事是重新安装 Windows。但是，嘿，至少现在它起作用了！
