QtQuick.Controls is not installed

[TyrannosourceExe]

Hi Everyone!

I inherited a QT project from a retired co-worker and I am building it for the first time on Ubuntu 16.04.6 desktop and am installing dependencies from scratch.

I incur the following error message during runtime.

QQmlApplicationEngine failed to load component
<qml_filepath>  module "QtQuick.Controls" is not installed

The project is running Python 2.7.12 with PyQt5, qt5-default 5.5.1, and the QML file calls for

import QtQuick 2.5
import QtQuick.Controls 1.4

I haven't been able to find much help on this matter so any advice is appreciated.
Thanks ahead of time.

Hi and welcome to devnet,

From the looks of it you haven't installed the corresponding package from your distribution.

qt5-defaults is haut part of it. Take a look at the others available through your package manager.
