Can't run fg_plane_view.sh

Hello.

I learned VTOL by ardupilot official quadplane docs.

and during I follow the instructions, I found that quadplane simulation can be visualized by below mehod.

https://ardupilot.org/plane/docs/quadplane-simulation.html

this link is simply saying using fg_plane_view.sh, the visualizing can be done, so I thought the visualizing is easy thing.

but actually it seems to be very complex.

when I run the script, I get below error messages.
