Unable to open the USB of UART console for testing the library examples

Hi all… I was trying to learn the code repository of Ardupilot and tried testing the example codes of the library on the sitl. I have sucessfully build the code but when I try to run the example usb or uart connection is not detected. I am uploading the image of the error…Any help will be much appreciated.

I was following the Ardupilot docs of Learning the code. Link: https://ardupilot.org/dev/docs/learning-ardupilot-the-example-sketches.html
