• This is because the first port in the list does not belongs to the arduino.
• So you have to go to the device manager and under port section you have to uninstall some ports.
• You need only uninstall the ports those are list before the arduino's com port.
• Example in command line port list shown in error is COM2 COM5 COM3 COM7
• And com 3 is for the arduino board.
• Then simply right click in COM2 line in the device manager window and click uninstall.
• Do the same for thr COM 5 

Note:- you no need to do it for the COM7
