我正在尝试将我的代码从 PyQt5 更改为 PySide2。我的大部分脚本只需将导入从 PyQt5 更改为 PySide2，它的工作原理是一样的。但是，我尝试将 Qt 文档中的许可向导示例从 PyQt5 改写为 PySide2。在 PyQt5 中它运行良好，但是，在 PySide2 中，我收到退出代码 139 的错误（被信号 11：SIGSEGV 中断）。PySide2 qwizard 代码用于线性向导，如类向导示例，工作正常。有谁知道为什么非线性向导会失败以及为什么会出现该错误？

谢谢

下面的代码适用于 PyQt5。用 PySide2 替换 PyQt5 我得到一个错误

进程以退出代码 132 结束（被信号 4：SIGILL 中断）

似乎与 PyQt5 不同，PySide2 要求您传递父级，在您的情况下，解决方案是更改类的构造函数：

class Some_Page(QtWidgets.QWizardPage):
    def __init__(self):
        super(Some_Page, self).__init__()

至：

class Some_Page(QtWidgets.QWizardPage):
    def __init__(self, *args, **kwargs):
        super(Some_Page, self).__init__(*args, **kwargs)

当我们添加一个页面时，我们将父级传递给他：

class Wizard(QtWidgets.QWizard):
    num_of_pages = 5
    (intro, class1, class2, class3, conclusion) = range(num_of_pages)

    def __init__(self, *args, **kwargs):
        super(Wizard, self).__init__(*args, **kwargs)
        self.setPage(self.intro, IntroductionPage(self))
        self.setPage(self.class1, ClassesPage1(self))
        self.setPage(self.class2, ClassesPage2(self))
        self.setPage(self.class3, ClassesPage3(self))
        self.setPage(self.conclusion, ConclusionPage(self))
        self.setStartId(self.intro)

完整代码：

class IntroductionPage(QtWidgets.QWizardPage):
    def __init__(self, *args, **kwargs):
