TypeError: metaclass conflict: the metaclass of a derived class must be a (non-strict)

Question

我的代码有什么问题？我正在尝试将我的 UI 文件与 python 连接起来。我几乎可以肯定所有事情，但我无法定义哪里出了问题。

from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.uic import loadUiType

ui = loadUiType('main.ui')


class MainApp(QMainWindow, ui):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setupUI(self)


def main():
    app = QApplication(sys.argv)
    window = MainApp()
    window.show()
    app.exex_()


if __name__ == '__main__':
    main()

我不确定 UI 文件加载的 'inheritance' 风格应该如何工作。但是，这应该可以满足您的要求：

from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.uic import loadUi


class MainApp(QMainWindow):
    def __init__(self, parent=None):
        super().__init__(parent)
        loadUi('main.ui', self)

def main():
    app = QApplication(sys.argv)
    window = MainApp()
    window.show()
    app.exec_()


if __name__ == '__main__':
    main()
