Quick fix is:

sudo pacman -S qt5-tools
sudo pacman -S qt5-quickcontrols
sudo pacman -S qt5-graphicaleffects

Your quick fix makes some sense, but I would prefer if it could work without those packages.

From a quick web search: could you try uninstalling them again and launching Pext as follows?
QML2_IMPORT_PATH=$HOME/.local/lib/python3.7/site-packages/PyQt5/Qt/qml pext?

[tastyminerals]

I am getting the same error with QML2_IMPORT_PATH var.
So no, it doesn't work.

Why wouldn't you go for an AUR package on Manjaro?

[TheLastProject]

Even then, the pip version should just work. This issue could affect other distros too.
