#样例
import sys
from PyQt5.QtWidgets import QApplication, QMessageBox


def main():
    app = QApplication(sys.argv)
    message_box = QMessageBox()
    message_box.setIcon(QMessageBox.Information)
    message_box.setText("Hello PyQt5!")
    message_box.setWindowTitle("Test")
    message_box.exec_()


if __name__ == "__main__":
    main()

报错：

Traceback (most recent call last):

from PyQt5.QtWidgets import QApplication, QMessageBox
