I am trying to build openuds and I get the error no module name cairo, I surfed a bit and found installing pycairo will solve it. 1) How do I fix this install error?

python manage.py createcachetable

2) Also in Java we have maven which will install the dependencies by its own like this any other tool is available for building python packages?

Pycairo is a Python bindings for the cairo graphics library. Pycairo doesn't provide precompiled binary wheels so pip has to compile it from sources. And to compile Pycairo you need cairo installed. So start with

apt install libcairo2

Or install the binding form your distribution:

apt install python-cairo
