subprocess.CalledProcessError: état de sortie non nul 0

Question

Quelle est la signification de cette erreur paradoxale?

subprocess.CalledProcessError: Command '/home/travis/build/fritzo/pomagma/build/debug/src/cartographer/cartographer' returned non-zero exit status 0

Il arrive quand je commence un sous-processus, puis dire que le sous-processus pour sortir proprement via une prise ZMQ. Il semble que, bien que zmq interroge, le processus se termine proprement (code de sortie 0), puis cette erreur est déclenchée.

est ici l'ensemble retraçage (d'un travis log):

Selon les docs, si votre sous-processus retourne non-zéro, alors il soulèvera cette exception. C'est aussi la convention standard sous Linux. https://docs.python.org/2/library/subprocess.html

Essayez d'inclure votre code client subprocess essayer: < ...> hic: < ...> enfin: sys.exit (0)
