我要import PyQt5.QtWebEngineWidgets，因为pip3 install PyQt5无法检测到我的Qt5安装（使用pip版本会导致找不到Qt_5_PRIVATE_API错误），所以我在CentOS上安装了python3-qt5的发行版软件包8台笔记本电脑如下：
python-qt5-rpm-macros.noarch 5.13.1-1.el8 @@System
python3-pyqt5-sip.x86_64 4.19.19-1.el8 @@System
python3-qt5.x86_64 5.13.1-1.el8 @AppStream
python3-qt5-base.x86_64 5.13.1-1.el8 @AppStream
python3-qt5-devel.x86_64 5.13.1-1.el8 @PowerTools
但是，没有针对CentOS的python3-qt5-webengine软件包，因此我尝试按照指南here从源代码进行构建，但出现错误：

Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into '/usr'.
Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
A suitable version of dbus could not be found.
QtWebEngine will not be built.
