python2 is not relevant, since krop is python3 only. The problem can be narrowed down to this code:
echo -e "from popplerqt5 import Poppler" | python3.7 On my system it loads python3-pyqt5 libs from /usr/lib/python3/dist-packages/PyQt5. May be try to play with PYTHONPATH to force python3 to pickup modules from /usr/lib/python3. Also in general I'd suggest to avoid using pip as root, install python modules locally with --user flag.
