NameError: name 'graph_draw' is not defined

After installing AUR package on arch-linux, it was an error during execution of simple piece of code.

makepkg -sri PKGBUILD (to install package)

because there was a strange error, trying to complie from source, so decide to use AUR.

  warnings.warn(msg, RuntimeWarning)

  File "lab_1.py", line 5, in <module>
    graph_draw(g, vertex_text=g.vertex_index)
NameError: name 'graph_draw' is not defined

shell returned 1

This what happens when I try to make, after manually install all recommended.

How to solve this on arch-linux?

Solution

  • From the No module named 'cairo' error in the traceback, I'd say you need to install cairo
