SIM_VEHICLE: MAVProxy exited SIM_VEHICLE: Killing tasks

[hamafathi]

Im new to this, and new to linux too. Im starting to learn Drones, and when I started this code : sim_vehicle.py --map --console I found this error! Any help please ?

SIM_VEHICLE: "mavproxy.py" "--master" "tcp:127.0.0.1:5760" "--sitl" "127.0.0.1:5501" "--out" "127.0.0.1:14550" "--out" "127.0.0.1:14551" "--map" "--console" RiTW: Starting ArduCopter : /home/hema/courseRoot/apm/ardupilot/build/sitl/bin/arducopter -S -I0 --model + --speedup 1 --defaults /home/hema/courseRoot/apm/ardupilot/Tools/autotest/default_params/copter.parm

Option “-e” is deprecated and might be removed in a later version of gnome-terminal.

Use “-- ” to terminate the options and put the command line to execute after it.

You're using a very old version of MAVProxy. Upgrade to the latest version and try again.

I tried this line of code : pip3 install mavproxy --user --upgrade

and this happened and the problem still the same

What version of Python is your default, ie python --version?

If you're running Python2, you'll need to run pip install mavproxy --user

[hamafathi]

python 3.8.10

Is there any other solution?

You've got an old version of MAVProxy somewhere in your system. Take a look at the current source code at https://github.com/ArduPilot/MAVProxy/blob/master/MAVProxy/mavproxy.py

Note that it doesn't match with your error message:

File "/usr/local/bin/mavproxy.py", line 12, in
import serial, Queue, select
ModuleNotFoundError: No module named 'Queue'

I see it. It worked for some reason! typing some codes trying to make python 2 is the default ans then python 3 udpate and upgrade with nothing new. finally, it worked, but again with some errors!
