[PyQt] PyQt5 error after re-install of Anaconda

[HARRIOTT, John]

Hi,

I have been using an Anaconda distro for Python 3.4. on RedHat 6.5
In order to write Qt5 compatible apps I built the appropriate SIP and PyQt5 modules.
My PyQt5 libs are located in my ~/.local/lib/python3.4/lib/PyQt5 folder.

All was good until Anaconda was re-installed. Now I get the following error when I run a python script that requires PyQt5 package:
"This application failed to start because it could not find or load the Qt platform plugin xcb".

I also notice the same error for other workstations that have Anaconda newly installed.

Any clues as to why this is occurring?

When I debug my script it succeeds in importing the packages, but dies when attempting to create a QApplication object.

I checked libqxcb has no missing dependents.
I rebuilt SIP and PyQt5

Below is a code example:

import sys
from PyQt5.QtWidgets import QApplication, QWidget

if __name__=='__main__':
               app = QApplication(sys.argv)
               w = QWidget()
               w.show()
               sys.exit(app.exec_())

Regards John
