On a Mac Mini M1 (ARM chip) with MacOS Monterey mavproxy.py fails:
$ mavproxy.py
Traceback (most recent call last):
File “/opt/homebrew/bin/mavproxy.py”, line 38, in
from MAVProxy.modules.lib import rline
File “/opt/homebrew/lib/python3.9/site-packages/MAVProxy/modules/lib/rline.py”, line 13, in

ImportError: dlopen(/opt/homebrew/lib/python3.9/sitepackages/gnureadline.cpython-39-darwin.so, 0x0002): symbol not found in flat namespace ‘_emacs_meta_keymap’
However, calling the interpreter on first mavproxy.py line, both imports work:
$ head -1 ‘which mavproxy.py’

So in SITL calling sim_vehicle.py… such as:
sim_vehicle.py -v ArduCopter -f quad -l 33.74111111,-118.37460000000002,44.0,270.0 --use-dir=BigW --console -m “–cmd=“module load misseditor;module load graph;graph RANGEFINDER.distance;param set DISARM_DELAY 0;calpress;batreset””*
gives above error, but executing compiled arducopter alone as in above:
build/sitl/bin/arducopter -S --model + --speedup 1 --slave 0 --defaults /Users/xxxxxx/Documents_outofthecloud/Desarrollo/GitHub/ardupilot/Tools/autotest/default_params/copter.parm -I0 --home 33.74111111,-118.37460000000002,44.0,270.0
works, and simulation can be done but without features depending on mavproxy.py.
I have done many reinstallations, but nothing has worked. What can I do?
Or a general reason for why those imports fail when called from mavproxy.py, but not when called from the interpreter called by mavproxy.py?
