No module named 'PyQt5.sip'

I tried following the directions in the README to build Electron Cash from source on a Ubuntu 18.04 VM. This was a new system, setup for experimenting with software.

When I got to the part where I run pyrcc5 icons.qrc -o gui/qt/icons_rc.py, I got this output:

trout@trout-wasabi:~/Electron-Cash$ pyrcc5 icons.qrc -o gui/qt/icons_rc.py

Try:

pip3 install --user -I PyQt5
pip3 install --user -I PyQt5-sip

-I tells it to ignore already-installed packages and reinstall them.

PyQt5.QtGui import * seems to be calling for SIP in some deprecated manner due to SIP no longer being bundled with PyQt5.

No… to the contrary – sip is bundled with PyQt5 as sip.so.

I made the follows:

pip uninstall pyqt5
pip install --upgrade pyqt5
