idea 启动时报 address already in use

系统开启hyper-v

1. Disable hyper-v (which will required a couple of restarts)
   dism.exe /Online /Disable-Feature:Microsoft-Hyper-V

2. When you finish all the required restarts, reserve the port you want so hyper-v doesn’t reserve it back
   netsh int ipv4 add excludedportrange protocol=tcp startport=<端口号> numberofports=1

3. Re-Enable hyper-V (which will require a couple of restart)
   dism.exe /Online /Enable-Feature:Microsoft-Hyper-V /All

when your system is back, you will be able to bind to that port successfully.

 

把端口号改成6942~6991间的任一个数字
