You will have to install ardupilot_gazebo first.

@ayushgaud After I installed ardupilot_gazebo, I still get an error.

[ayushgaud]

You can safely ignore that error. Is the Gazebo simulator starting properly?

[BreederBai]

@ayushgaud The Gazebo simulator started up normally. I found a new problem. The plane crashed into the roof after taking off, like this.

[ayushgaud]

You need to change the mode to guided and then execute takeoff 1 or something to take off to a certain height which should be less than the height of the gas station.

it is hard to control, it is always moving when i am doing nothing, and it often out off controling and crashes after i run the takeoff command
