J'ai du mal à installer pymunk sur mon Ubuntu 16.04. J'utilise virtualenv, j'ai installé Python 3.5.2, pymunk 5.3.0 et cffi 1.11.0.Pymunk dessin utils ne fonctionne pas
J'ai d'abord essayé un code très simple; Fondamentalement, j'ai créé un vide Space et a appelé step dessus et tout a fonctionné sans heurt. Cependant, lorsque j'essaie de le visualiser et de créer l'instance DrawOptions, j'obtiens des erreurs étranges, que je ne peux pas déchiffrer. En outre, j'ai essayé matplotlib_util et pygame_util, mais les deux n'ont pas réussi à créer DrawOptions.
Ceci est l'extrait de code je:
import pymunk
import pyglet
import pymunk.pyglet_util
s = pymunk.Space()
options = pymunk.pyglet_util.DrawOptions()
s.debug_draw(options)
# s.step(0.02)
Ceci est la sortie je reçois:

Que pensez-vous est à l'origine que? Est-ce la version python que j'utilise, ou peut-être que la compilation de cffi est défectueuse?
