I'm installing pyside2-tools in Ubuntu 16.04 using the pyside2-tools package by Thomas Pietrowski and when I do this I notice that the pyside2uic Python module gets installed on the path which should be used for Python 3... even if I only have Python 2 installed in the system.
This causes the pyside2-uic executable to complain about not finding the pyside2uic module:
I initially contacted Thomas because I figured maybe something was wrong with his "pyside2-tools" package for Ubuntu 16.04. He, however, asked me kindly to make a bug report here instead as he suspected something was not right with the CMake files.
As a workaround, it works fine to copy the pyside2uic Python module from /usr/lib/python3/dist-packages/ to /usr/local/lib/python2.7/dist-packages
