OR, find a repo which has the version of qt5-qtwebkit which you need to satisfy the requirements of what base repo has, enable that repo, and install…  or find the correct RPM, and use yum to install the RPM so yum has a record of the RPM.  Decisions, decisions...

I’ve done some digging and I see the problems.

I’ve also read that there have been some issues with qt5 5.9, so rather than try to go up to that version, let’s go back down to 5.6 version.  Supposedly, it does still exist in base repo, but I am unaware of how to select it manually.  From what I see, it’s for CentOS 7.4.1708, and yours may be newer at this point.  Worst case scenario is you download the packages you need (base, declarative, etc) and install those using yum against the RPM files, and then use epel repo to install the webkit, which fails due to dependencies from base repo.

The problem appears that qt5-qtwebkit has not been updated in epel, where base and declarative and others have been updated in base.

Good luck!

Mike
