Hi everyone,

I am new to ardupilot. I followed the instruction to run the SITL, however, an error stopped me when I run "sim_vehicle.py -w". Here is the error information.

SIM_VEHICLE: Run MavProxy
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"

Does anybody know how to solve this? Thanks so much!
