致命的 Python 错误：PyQt5.QtCore：无法嵌入 qt.conf

Question

我一直在使用 PyQt5 创建一个 GUI 应用程序。这个应用程序在几周前运行良好，但现在它显示了一个致命错误。我认为它无法导入 qt.core。我什至尝试创建一些基本应用程序，但仍然出现此错误。

以下是应用程序的代码：

import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QPushButton, QWidget, QAction, QTabWidget,QVBoxLayout,QLabel

#Creating the main window
class App(QMainWindow):
    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 - QTabWidget'
        self.left = 0
        self.top = 0
        self.width = 300
        self.height = 200
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)

        self.tab_widget = MyTabWidget(self)
        self.setCentralWidget(self.tab_widget)

        self.show()

#Creating tab widgets
class MyTabWidget(QWidget):
    def __init__(self, parent):
        super(QWidget, self).__init__(parent)
        self.layout = QVBoxLayout(self)

        #Initialize tab screen
        self.tabs = QTabWidget()
        self.tab1 = QWidget()
        self.tab2 = QWidget()
        self.tab3 = QWidget()
        self.tabs.resize(300,200)

        #Add tabs
        self.tabs.addTab(self.tab1,"Tab1")
        self.tabs.addTab(self.tab2,"Tab2")
        self.tabs.addTab(self.tab3,"Tab3")

        #Create first tab
        self.tab1.layout = QVBoxLayout(self)
        self.l = QLabel()
        self.l.setText("This is the first tab")
        self.tab1.layout.addWidget(self.l)
        self.tab1.setLayout(self.tab1.layout)

        #Add tabs to widget
        self.layout.addWidget(self.tabs)
        self.setLayout(self.layout)

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

这不是我的应用程序，它是一个基本的 GUI，它显示相同的错误。 它显示的错误如下：

Fatal Python error: PyQt5.QtCore: Unable to embed qt.conf
AttributeError: module 'PyQt5' has no attribute '__file__'

我运行了这个程序，它工作正常。如果您使用 python 2 或旧的 pyqt 版本，则可能会出现此错误。看来你应该更新了。如果不是这样，请告诉我，请告诉我
