我正在尝试编译 PyQT5，但我需要包含这些模块，有人对如何重新配置以包含这些模块有任何想法吗？
cd E:\QT\5.15.2\Src\qtwebengine
E:\QT\5.15.2\Src\qtwebengine>E:\QT\5.15.2\msvc2019_64\bin\qmake WEBENGINE_CONFIG+=use_proprietary_codecs
输出日志：

WARNING: Python version 2 (2.7.5 or later) is required to build QtWebengine.
WARNING: Python version 2 (2.7.5 or later) is required to build QtPdf.
WARNING: QtWebEngine will not be built.
WARNING: QtPdf will not be built.
Qt is now configured for building. Just run 'nmake'.
Once everything is built, you must run 'nmake install'.
Qt will be installed into 'E:\QT\5.15.2\msvc2019_64'.
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
我不得不从 Windows 环境中删除 python 3 的其他安装，只保留 2.7，而不是完全删除构建目录。修改后保存的缓存没有更新（bug），需要删除。 参考
