Question

我已经安装了dronekit和dronekit sitl并创建了hello.py示例，我得到以下的错误我是新手，很抱歉，如果它显而易见的话。这是我在debian下使用python 2.7在raspberry 3上运行的输出。这是代码

print "Start simulator (SITL)"
import dronekit_sitl
sitl = dronekit_sitl.start_default()
connection_string = sitl.connection_string()

# Import DroneKit-Python
from dronekit import connect, VehicleMode

# Connect to the Vehicle.
print("Connecting to vehicle on: %s" % (connection_string,))
vehicle = connect(connection_string, wait_ready=True)

# Get some vehicle attributes (state)
print "Get some vehicle attribute values:"
print " GPS: %s" % vehicle.gps_0
print " Battery: %s" % vehicle.battery
print " Last Heartbeat: %s" % vehicle.last_heartbeat
print " Is Armable?: %s" % vehicle.is_armable
print " System status: %s" % vehicle.system_status.state
print " Mode: %s" % vehicle.mode.name    # settable

# Close vehicle object before exiting script
vehicle.close()

# Shut down simulator
sitl.stop()
print("Completed")

这是我得到的输出：



python hellp.py
Start simulator (SITL)

SITL already Downloaded and Extracted.

    sitl.launch(sitl_args, await_ready=True, restart=True)

    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1024, in _execute_child

非常感谢您的任何帮助

当您在 ARM 上运行 SITL 时，这可能是问题所在。您可能已经通过 apt-get 直接安装了软件包。您可以尝试在 pi 本身上构建 SITL，然后尝试运行。
