QML Import Path issue

[LS-KS]

Hey
I Have several Singleton classes and exported them with:

QML_IMPORT_NAME = "io.qt.textproperties"
QML_IMPORT_MAJOR_VERSION = 1

This actually never changed and the path itself was generated from Qt Creator.

In QML I import them like:

import io.qt.textproperties 1.0

At some point everything was running and I wanted to rename a Python class before I commit.
Well... after renaming the Python class and renaming also the qml files nothing works.

QQmlApplicationEngine failed to load component
file:///Users/.../view/main.qml:5:1: module "io.qt.textproperties" is not installed

I deleted the folder 'io' and hoped to get it recreated by Qt Creator. I also deleted pycache folder even restarted my machine ... but nothing works.
I also asked copilot to analyze my error but he also says everything is fine.

I have now commited to this repository although application is not running: link

I appreciate every hints :-)

stupid me:

Since main.py doesn't refer to anything from controller.py it was labelled as unused import.
I didn't think when I hit the shortcut to optimize imports.

I created a new project as minimal example.
This should work right?

main.py:

# This Python file uses the following encoding: utf-8
import sys
from pathlib import Path

from PySide6.QtGui import QGuiApplication
from PySide6.QtQml import QQmlApplicationEngine


if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()
    qml_file = Path(__file__).resolve().parent / "main.qml"
    engine.load(qml_file)
    if not engine.rootObjects():
        sys.exit(-1)
    sys.exit(app.exec())

Controller.py

# This Python file uses the following encoding: utf-8
from PySide6 import QtCore
from PySide6.QtQml import QmlElement, QmlSingleton

QML_IMPORT_NAME = "io.qt.textproperties"
QML_IMPORT_MAJOR_VERSION = 1

@QmlElement
@QmlSingleton
class Controller(QtCore.QObject):

    addedOne = QtCore.Signal(int)

    def __init__(self, parent = None):
        super().__init__(parent)

    @QtCore.Slot(int)
    def addOne(self, value: int):
        self.addedOne.emit(value + 1)

main.qml

import QtQuick
import QtQuick.Window
import QtQuick.Layouts

import io.qt.textproperties 1.0

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

    Column{
        TextField{
            id: input
            text: 0
            Connections{
                target: Controller
                function onAddedOne(result){
                    text = result
                }
            }
        }
        Button{
            text: "add one"
            onClicked: Controller.addOne(input.text)
        }
    }
}

Output:

QQmlApplicationEngine failed to load component
file:///Users/.../qmlelementtest/main.qml:5:1: module "io.qt.textproperties" is not installed

the folder io.qt.textproperties is only created when I use QtCreators build functionality. With PyCharm / VsCode there will be no directory created which contains qmldir.
