QML Module Not Found QtQuick.Window

MH24

Trying to make a simple QtQuick project. But running into this error when I Build. Using Qt Creator 6.0.2 Based on Qt 5.15.3 (GCC 11.2.0, 64 bit)
Linux, Ubuntu 22.04.
The error is in main.qml which is as follows:

import QtQuick 2.15
import QtQuick.Window 2.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
}

I have added /usr/lib/x86_64-linux-gnu/qt6/qml to the QML_IMPORT_PATH in the .pro file.

How do I fix this?

QML_IMPORT_PATH

QML_IMPORT_PATH is for your own QML modules, not for /usr/lib/x86_64-linux-gnu/qt6/qml. What is the error message?

@JoeCFD Error is: Unknown module(s) in QT:quick

JoeCFD

@MH24 can you show your pro file here?

MH24

@JoeCFD

QT += quick


SOURCES += \
        main.cpp

RESOURCES += qml.qrc

QML_IMPORT_PATH = 

QML_DESIGNER_IMPORT_PATH =

qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

install qt5-qtdeclarative-devel

@JoeCFD I did that. Still same error

JoeCFD

@MH24 install qtquickcontrols2-5-dev as well.

I am trying the qt6 book and discovered something regarding kits.

Made the Qt Quick UI Project and it created a qmlproject and qml file (with same error as above). When I hovered on the project it said 'No kits are available for this project'. When I went to 'Projects' tab on left it opens 'Configure Project' says 'No suitable kits found' and 'Desktop' under kits is greyed out.

What does this mean?

JoeCFD

add other two into your pro file. BTW. from Qt6 cmake is preferred, I guess.
QT += qml quick quickwidgets

So I created a new kit by manually pointing to Qt 5.15.3 (qt5) instead of Qt 6.2.4. Qt QUick UI Project works fine but others still do not even when I point them to this kit.

JoeCFD

@MH24 Qt 6.2.4 is too new for Qt6. Try Qt6.4 or above. if you use Qt6, drop the version numbers in the rows of import.

import QtQuick 
import QtQuick.Window

Window {
   width: 640
   height: 480
   visible: true
   title: qsTr("Hello World")
}
