Unable to install dronekit on pi4, Missing depedancies

[Radnartjie]

I'm having a bit of trouble installing python dronekit on my raspberry pi 4B (8GB) (bullseye).

I know that dronekit does not support Python3, hence I am running a virtual python environement (dronekitty)

This is my terminal output:

What could i be doing wrong? I am pretty new to Linux.

Have You Tried Installing libxml2 and libxslt packages?

[Radnartjie]

try this "sudo apt-get install libxml2-dev libxslt1-dev zlib1g-dev python-py"
or you can try "sudo aptitude dronekit",this command can guide you to install dronekit.
