1. 从源代码运行代码：

$ python web_browser_main.py

（站点显示正确）

导入PyQt5时出现结果错误。QtWebKitWidgets

msys2 mingw64控制台中的所有内容。如何编译上述文件？

Answer 1

pyinstaller --onefile --hidden-import PyQt5.QtWebKit web_browser_main.py

上面的代码包括丢失的模块QtWebKit。我建议使用--onedir而不是--OneFile，因为我认为输出exe更稳定。（在像web\u browser\u main应用程序这样的应用程序中，我在几秒钟后出现了运行时错误）

现在工作！！！
