pylint erreur PyQt4

Question

J'écris un programme:

from PyQt4.QtCore import * 
from PyQt4.QtGui import * 

def main(): 
    app = QApplication([]) 
    button = QPushButton("hello?") 
    button.show() 
    app.exec_() 

if __name__=="__main__": 
    main() 

le nom du fichier est t.py, quand je lance:

pylint t.py 

à ubuntu9.10, pyqt4, je suis arrivé ceci:

pylint t.py 
No config file found, using default configuration

dans windows XP, avec pythonxy,

J'ai seulement reçu un message d'erreur, pourquoi?

Answer 1

On dirait un bogue dans astng. Ils essaient de lire le nom d'une fonction qui ne le publie pas (fonction d'extension native). Je signalerais un bug à la fois astng et pyqt projets. Le premier serait qu'ils devraient mieux gérer une situation sans nom. Le second serait que chaque extension sensée devrait publier au moins les noms des fonctions.

Answer 2

Je voudrais vérifier si vous utilisez la toute dernière astng, pylint, etc.
