module "QtQuick.Controls" version 2.2 is not installed

Zlamir

Hi, i'm new to Qt and i was following this video tutorial to make a simple to do list app.
In that video, a Qt Quick Controls 2 Application is created, but i noticed was that in my QtCreator version that option was not available.
So, the apparent solution was to import the required prerequisites given by the official documentiation:

import QtQuick.Controls 2.2 .qml file.
#include <QtQuickControls2> in the .cpp file.
QT += quickcontrols2 in the .pro file.

The thing is when i try tu run it i get the error:

QQmlApplicationEngine failed to load component
qrc:/main.qml:3 module "QtQuick.Controls" version 2.2 is not installed

Also i think 'm using the right versions of each module according to the docs:

Qt: 5.9
QtQuick: 2.9
QtQuickControls: 2.2

I appreciate any help or advice.

Change the import statement in .qml file to 2.1 instead of 2.2

`import QtQuick.Controls 2.1`

It throws the same error but now asking for the version 2.1.

@Zlamir How did you install Qt?

Zlamir

Well, i didn't found an official installing guide for Ubuntu 18.04 so i followed this one.
The steps to install QtCreator were basically:

sudo apt install build-essential
sudo apt install qtcreator
sudo apt install qt5-default

Then, to use QtQuickControls i was missing some dependencies that i had to install mannually through running:

sudo apt install qtdeclarative5-dev
sudo apt install libgles2-mesa-devqtquickcontrols2-5-dev
sudo apt install qtquickcontrols2-5-dev

PD: Sry for the late response but i was a little busy with new year stuff.

Thank you! Installing from the official source actually solved the issue.

Hi,
I'm using QT_VERSION 5.9.5, both qtdeclarative5-dev and qtquickcontrols2-5-dev are already the newest version (5.9.5-0ubuntu2).
Also added those lines in cpp, qml and pro file as Zlamir mentioned, but still getting the "module "QtQuick.Controls" version 2.2 is not installed" error.

What else should I check?

Edit: Funny thing - switching to QtQuick.Controls 1.4 works..

Bug fix for Debian 10 and default Qt5.11:
sudo apt install qml-module-qtquick-controls2
