我有一个问题.当我重新启动计算机时,“扑医生”就可以了.我可以成功运行我的应用程序.但是,一旦我运行我的应用程序,命令“颤动医生”是错误的.如果我重新启动计算机,“颤动的医生”将再次恢复正常.是谁遇到了同样的问题,如何解决它

例外：idevice_id返回错误：

最佳答案 这是一个
upstream bug in libusbmuxd
will be fixed soon.还有一个
proposed workaround被认为包含在Flutter本身.

同时,GitHub用户@mattijsf mentioned有几种解决问题的方法：

>取消配对可能位于曾与Xcode配对的同一本地(Wi-Fi)网络中的任何不需要的iOS设备,方法是将其与USB连接,然后：打开Xcode>窗口>装置&模拟器>右键单击设备>取消配对设备.
>如果您使用的是不想从Xcode取消配对的物理iOS设备,则必须使用USB电缆连接它或在设备上禁用Wi-Fi.

No device found with udid 4a8e882c613--37cc1ac48, is it plugged in?

# Attaching device with USB

$idevice_id -l

....etc

# Now it works
