我一直在使用PyQt5创建GUI应用程序。这个应用程序在几周前运行完美,但是现在显示出致命错误。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,但仍然会发生此错误。
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,它是基本的GUI,它显示相同的错误。它显示的错误在下面给出:
Fatal Python error: PyQt5.QtCore: Unable to embed qt.conf

我运行了该程序,它可以正常工作。如果您使用的是python 2或旧的pyqt版本,则可能出现此错误。看来您应该进行更新。如果不是这样,请告诉我]
