3556	A problem starting chimerax on Centos7	mohamad.harastani@…	Greg Couch	"{{{
Hello,

I installed chimreax on Centos7 today (28/07/2020). I downloaded the rpm
package on the website for Latest Production Release for Centos7.
The installation completed, but I had the following error when I try to
start chimerax:

[guest@rosen ~]$ chimerax
Traceback (most recent call last):
  File ""/opt/UCSF/ChimeraX/lib/python3.7/runpy.py"", line 193, in

    exit_code = init(sys.argv)

    sess.ui = ui_class(sess)
  File ""/opt/UCSF/ChimeraX/lib/python3.7/site-packages/chimerax/ui/gui.py"",
line 116, in __init__
    import PyQt5.QtWebEngineWidgets
ImportError:
/opt/UCSF/ChimeraX/lib/python3.7/site-packages/PyQt5/Qt/lib/libQt5WebEngineWidgets.so.5:
symbol _ZN12QQuickWidget18focusNextPrevChildEb, version Qt_5 not defined in
file libQt5QuickWidgets.so.5 with link time reference


I tried that with two computers having centos7, and got exactly the same
error.

Also, I tried the rpm package for centos7 from the Daily Builds and it
gives the same error.
