它看起来令人窒息的那一行是在 character_info_window 模块中 CharacterInfowWindow 类(QtWidgets.QMainWindow 的子类)的 __init__() 函数中调用super".关于可能是什么问题的任何想法?

The line it looks to be choking on is a call to "super" within the __init__() function of the CharacterInfowWindow class (subclass of QtWidgets.QMainWindow) within the character_info_window module. Any ideas on what could be the problem?

推荐答案

我今天也遇到了这个问题.我的解决方案是在我的测试目录中创建一个 pytest.ini 文件并将其包含在其中.

I had this issue today as well. The solution for me was to create a pytest.ini file in my tests directory and include this in it.

[pytest]
qt_api=pyqt5

来自 https://github.com/pytest-dev/pytest-qt

要强制使用特定的 API，请将 pytest.ini 文件中的配置变量 qt_api 设置为 pyqt5 或 pyside2

To force a particular API, set the configuration variable qt_api in your pytest.ini file to pyqt5 or pyside2

在 pytest.ini 中设置 qt_api 后，测试运行没有任何问题

Once I set the qt_api in the pytest.ini the tests ran without any issues
