Ubuntu QT install qt quick controls 2.1

Question

I have a Qt 5.7.0 application. When I run my application it does not start and there is a terminal message saying:

QQmlApplicationEngine failed to load component
qrc:/main.qml:2 module "QtQuick.Controls" version 2.1 is not installed

How can I solve this issue?

Thanks!!

@eyllanesc Following this guide https://wiki.qt.io/Install_Qt_5_on_Ubuntu until command sudo "apt-get install libglu1-mesa-dev -y", nothing more — Ale, Aug 04 '17 at 14:51
change `import QtQuick.Controls x.y` to `import QtQuick.Controls 1.4` — eyllanesc, Aug 04 '17 at 14:55
@eyllanesc but I need qml properties that the 1.4 does not accept... — Ale, Aug 04 '17 at 14:57
For this you need the latest version of Qt, download version 5.9: http://download.qt.io/official_releases/qt/5.9/5.9.1/qt-opensource-linux-x64-5.9.1.run — eyllanesc, Aug 04 '17 at 15:00
Ubuntu 18.04, this fixed it for me: sudo apt-get install qml-module-qtquick-controls2 — Luke Dupin, Apr 08 '19 at 18:26

As you can see from the "Versions" section of the Qt Quick Controls 2 documentation, you have to import version 2.0 of Quick Controls if you're using Qt 5.7, not version 2.1 of Quick Controls.

Alternatively, you could update to the latest version of Qt (5.9), and then you can use Quick Controls 2.1.

Your answer doesn't state how someone would update to Qt 5.9 – Starbuck Mar 15 '19 at 20:01
