pyQML 文件对话框：未安装模块"Qt.labs.folderlistmodel"

Question

我试图在QML中添加FileDialog，我的环境:

Python 3.10.8

• PyQt6
• Arch Linux
• qt6-base,qt6-declarative包安装
代码:

main.qml

import QtQuick 
import QtQuick.Window 
import QtQuick.Controls 
import QtQuick.Dialogs
Window {
Rectangle {
id: mainRect
anchors.fill: parent
Button {
text: qsTr("Open File")
onClicked: fileDialog.open()
}
}

FileDialog {
id: fileDialog
}
}

main.py

import os
import sys
from PyQt6.QtGui import QGuiApplication
from PyQt6.QtQml import QQmlApplicationEngine

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

当我尝试运行时，它会产生以下错误:

file:///main.qml:20:5: QML FileDialog: Failed to load non-native FileDialog implementation:
qrc:/qt-project.org/imports/QtQuick/Dialogs/quickimpl/qml/FileDialog.qml:4 module "Qt.labs.folderlistmodel" is
not installed
Segmentation fault (core dumped)

我试着搜索包的repo和pypi，看看是否有一个额外的包包含这个文件夹列表模型，但我找不到任何。

Answer 1

我在Windows上尝试过FileDialog，它工作得很好，这似乎是一个Arch Linux包装问题，但我不确定在哪里报告。我使用tkinter在这个答案中提到的解决方案，它在两个操作系统上都能很好地工作。

Answer 2

必须安装pyside6:

export QML2_IMPORT_PATH=/usr/local/lib/python3.8/site-packages/PySide6/Qt/qml

在码头工人:

ENV QML2_IMPORT_PATH=/usr/local/lib/python3.8/site-packages/PySide6/Qt/qml
