Hello everyone. I see the following error when attempting to install pymavlink:
user@user-XPS-15-9570:~/src/Firmware$ sudo pip install pymavlink pyserial

I tried to set the MDEF environment variable:
user@user-XPS-15-9570:~/src/Firmware/mavlink/include/mavlink/v2.0/message_definitions$ export MDEF=`pwd`
user@user-XPS-15-9570:~/src/Firmware/mavlink/include/mavlink/v2.0/message_definitions$ echo $MDEF
/home/user/src/Firmware/mavlink/include/mavlink/v2.0/message_definitions
I installed all the dependencies but I’m unsure how to proceed now.
