from PyQt5.QtWidgets import QPushButton class PushButton(QPushButton): pass

class DropDownButtonBase: pass

class btn1(DropDownButtonBase,PushButton): pass print(btn1)

很迷，这样就直接崩溃。py3.12。

[zhiyiYo]

换成 pyqt6 试试

[HIllya51]

解决了。更新pyqt5的版本到最新版就行了。

另外我好像写错了，我前面是PyQt5-Qt5是5.15.2，PyQt5是5.15.7。更新PyQt5到5.15.10就行了。看起来似乎是PyQt5的旧版本（不过也不是很旧）有bug吧。

py3.11和py3.12都用PyQt5==5.15.7，py3.11就没问题，py3.12就有问题。

[zhiyiYo]

应该旧版本 pyqt 不支持 py312
