(尝试在命令行中添加 '--allowerasing' 来替换冲突的软件包 或 '--skip-broken' 来跳过无法安装的软件包 或 '--nobest' 来不只使用软件包的最佳候选)
系统安装的有libQt5Gui.so.5，
[root@Longxi ~]# locate libQt5Gui.so.5
/usr/lib64/libQt5Gui.so.5
/usr/lib64/libQt5Gui.so.5.15
/usr/lib64/libQt5Gui.so.5.15.2
[root@Longxi ~]# rpm -qa|grep qt5
qt5-qtbase-5.15.2-3.an8.x86_64
qt5-srpm-macros-5.12.5-3.el8.noarch
qt5-qtbase-gui-5.15.2-3.an8.x86_64
qt5-qtbase-common-5.15.2-3.an8.noarch
希望能更新安装方法或能给点建议，谢谢！
