J'essaie de capturer le package d'un projet non-pur python. J'ai utilisé le plug-in python
avec des scripts de génération/installation personnalisés.
Ce projet contient 2 python packages requis pour l'application de bureau:
alfanous
(API)alfanous-desktop
_ (interface graphique Qt PySide)snapcraft.yaml
fichier:
_name: alfanous
version: "0.7.8"
summary: Alfanous
description: GNU hello prints a friendly greeting.
This is part of the snapcraft tour at http://snapcraft.io/create/

Le paquet logiciel enfichable est construit et installé sans erreur. Cependant, si j'essaye de l'exécuter:
_$ alfanous.alfanous-cli

Mon premier suspect est non complet PYTHONPATH
, en essayant de déboguer:
_snap run --Shell alfanous.alfanous-cli
env | grep -i python
_
n'apporte rien.
et les deux paquets sont là:
_$ ls /snap/alfanous/current/usr/lib/python2.7/site-packages/
alfanous alfanousDesktop
alfanous-0.7.29-py2.7.Egg-info alfanousDesktop-0.7.29-py2.7.Egg-info
_
Comment configurer correctement PYTHONPATH
? Le plugin python ne devrait-il pas s'en charger?
snapcraft v2.28 Ubuntu 16.04.2 LTS 64Bit
J'ai modifié alfanous-console
pour imprimer sys.path
et reconstruire le cliché:
['/snap/alfanous/x4/usr/bin',
'/snap/alfanous/x4/usr/lib/python2.7',
'/snap/alfanous/x4/usr/lib/python2.7/plat-x86_64-linux-gnu',
'/snap/alfanous/x4/usr/lib/python2.7/lib-tk',
'/snap/alfanous/x4/usr/lib/python2.7/lib-old',
'/snap/alfanous/x4/usr/lib/python2.7/lib-dynload',
'/snap/alfanous/x4/usr/lib/python2.7/dist-packages']
Il semble clair que la snap
n'inclut pas site-packages
à PYTHONPATH
où mon paquet cible s'installe.
Ou signalez-le à l’équipe instantanée pour ajouter usr/lib/python2.7/site-packages
En relation Rapport de bug n ° 1670749: le confinement classique nécessite le paramétrage manuel de PATH et PYTHONPATH
La solution suggérée n'a pas fonctionné:
apps:
alfanous-gui:
command: usr/bin/alfanous-desktop
environment:
PATH: $SNAP/usr/bin:$SNAP/bin/:$PATH
PYTHONPATH: $SNAP/usr/lib/python2.7/site-packages:$SNAP/usr/lib/python2.7/dist-packages:$PYTHONPATH
#desktop: usr/share/applications/my-app.desktop
alfanous-cli:
command: usr/bin/alfanous-console
environment:
PATH: $SNAP/usr/bin:$SNAP/bin/:$PATH
PYTHONPATH: $SNAP/usr/lib/python2.7/site-packages:$SNAP/usr/lib/python2.7/dist-packages:$PYTHONPATH
