pylint PyQt4型

Question

我写了一个程序：

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

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

if __name__=="__main__":
    main()

文件名是t.py， 当我跑步时：

^{pr2}$

在ubuntu9.10，pyqt4中， 我知道了：

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

我只收到一条错误信息，为什么？在

Answer 1

我会检查你是否使用最新的astng、pylint等

Answer 2

似乎是astng中的错误。他们试图读取不发布的函数的名称（本机扩展func）。我会向astng和pyqt项目报告一个bug。首先，他们应该更好地处理无名的情况。第二种方法是每个正常的扩展至少应该发布函数名。在
