Compatibility issues between PX4 software package and MRS_UAV

[yuan99993]

Hello, I would like to ask if the MRS_UAV is incompatible with the PX4 flight control files? Because when I first downloaded MRS_UAV, I already had the PX4 software package installed on my computer, and when I ran ./start.sh in the example, the situation shown in the picture occurred. After I deleted the related PX4 flight control software package, it worked normally.
