Python PyQT5 WebEngine Segmentation fault 错误
Python PyQT5 WebEngine Segmentation fault Error
我想创建一个应用程序来下载 ms store 应用程序，它 运行 很好，直到今天我尝试打开该网站 (https://apps.microsoft.com/) pyqt5 window 崩溃并且它显示 'Segmentation fault'，当我尝试加载像 microsoft.com 或 google.com 这样的页面时它工作正常当我在 microsoft.com 和页面 returns 中搜索应用程序时崩溃以 'https://apps.microsoft.com/...' 开头的 url 它因 'Segmentation fault' 错误
而崩溃

我基本上克隆了 geeksforgeeks 简单浏览器 (https://www.geeksforgeeks.org/creating-a-simple-browser-using-pyqt5/) 并对其进行了更改，因此它的行为也相同我认为微软对站点进行了一些更改，因为它昨天运行良好。
谁能帮我解决这个问题，我想从网站上获取 url 的应用程序。
好吧，我找到了问题的答案，答案只是升级到最新的 pyqt6(https://pypi.org/project/PyQt6/) and use pyqt6-webengine(https://pypi.org/project/PyQt6-WebEngine/), the pyqt5-webengine was implemented using chroimium 87 and the pyqt6-webengine was implemented using chromium 90 (https://wiki.qt.io/QtWebEngine/ChromiumVersions)，它会自动将 http 请求升级到 https。
在 pyqt5 中我得到了这个错误

我在胡说这意味着它无法处理请求，因为它是作为 http 请求和站点 运行 https 发出的，因此应用程序自 pyqt5-webengine（旧版本的铬）以来崩溃了没有自动将 http 请求升级为 https。
升级到pyqt6后

所以在我更改为 pyqt6 之后出现了同样的错误，但它没有崩溃并给我错误代码，而是自动将请求升级到 https（因为它使用了更新版本的铬）。我想如果你能以某种方式让 pyqt5 使用最新版本的铬，它应该可以工作，但我不知道它是否可能或如何做。
如果我错了，请随时纠正我。我不是 python 或 pyqt 方面的专家，但是升级到 pyqt6 的这个解决方案对我有用并解决了我的问题。
