从另一个文件打开 GUI 时键入错误

Question

尝试在另一个文件中打开 pyqt5 GUI 时出现错误。

main.py

from main_scrn import Ui_MainWindow
from sload_page import Ui_SLoadWindow
from PySide2.QtWidgets import *

class SLoadWindow(QMainWindow):
    def __init__(self, parent=None):
        QMainWindow.__init__(self, parent)
        self.ui = Ui_SLoadWindow()
        self.ui.setupUi(self)

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    window = SLoadWindow()
    sys.exit(app.exec_())

sload_page.py

我对 PyQt5 知之甚少，因为我对它还很陌生，而且厌倦了 tkinter，所以如果你能告诉我任何事情或提出改进建议，那将非常有帮助，我将不胜感激。

问题是您错误地组合了库。尽管 PyQt5 和 PySide2 是 Qt 的绑定，但它们是不同的实现，因此它们不兼容，因此解决方案：

或使用PyQt5：在main.py
中改为from PyQt5.QtWidgets import *
或使用 PySide2 但不能同时使用：在 sload_page.py
中更改为 from PySide2 import QtCore, QtGui, QtWidgets

但不要同时使用这两个库。
