AttributeError的：“Ui_MainWindow”对象有没有属性“setCentralWidget” PyQt5

我仍然在GUI上为我的数据库工作，现在我有一个不同的错误：AttributeError的：“Ui_MainWindow”对象有没有属性“setCentralWidget” PyQt5

Traceback (most recent call last): 
    File "G:\Python\Database Kast Thuis\PyQt Test\MainMenu_ui.py", line 84, in <module> 
    ex = Ui_MainWindow() 
    File "G:\Python\Database Kast Thuis\PyQt Test\MainMenu_ui.py", line 16, in __init__ 
    self.setupUi(self) 
    File "G:\Python\Database Kast Thuis\PyQt Test\MainMenu_ui.py", line 55, in setupUi 
    MainWindow.setCentralWidget(self.centralwidget) 
AttributeError: 'Ui_MainWindow' object has no attribute 'setCentralWidget'

我不明白的事关于PyQt，所以我不明白是什么问题。

的代码是：（这是编辑的版本，原始版本在下面发布）

是什么原料？什么是编辑？你用'pyuic'编辑生成的文件吗？为什么？什么版本不起作用？ – m0nhawk

Raw未经编辑，是我编辑的文件。因为否则它不会反正跑。两个版本都不。原始的不知道如何显示屏幕和编辑的错误。我想修改编辑的一个... –

Pyuic没有作出转换程序运行。它只是产生屏幕外观的数据。进一步它不告诉程序如何运行自己。 –

Qt设计用来生成视图的设计，pyuic5转换是设计进入python代码，这个元素必须和逻辑一起使用，另外建议不要修改它。

第一个解决方案：

import sys 

if __name__ == "__main__": 
    app = QtWidgets.QApplication(sys.argv) 
    ex = Ui_MainWindow() 
    w = QtWidgets.QMainWindow() 
    ex.setupUi(w) 
    w.show() 
    sys.exit(app.exec_())

二解决方案：

class MainWindow(QtWidgets.QMainWindow): 
    def __init__(self, parent=None): 
     super(MainWindow, self).__init__(parent=parent) 
     ui = Ui_MainWindow() 
     ui.setupUi(self) 


import sys 

if __name__ == "__main__": 
    app = QtWidgets.QApplication(sys.argv) 
    w = MainWindow() 
    w.show() 
    sys.exit(app.exec_())

解决方案三：

class MainWindow(QtWidgets.QMainWindow, Ui_MainWindow): 
    def __init__(self, parent=None): 
     super(MainWindow, self).__init__(parent=parent) 
     self.setupUi(self) 



import sys 

if __name__ == "__main__": 
    app = QtWidgets.QApplication(sys.argv) 
    w = MainWindow() 
    w.show() 
    sys.exit(app.exec_())
