python - 如何在 QML 中使用 QtWebEngine

Question

我想在 QML 中与 PyQT 一起使用 QtWebEngine。我正在尝试运行简单的示例。

import sys
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication, QWidget
from PyQt5.QtQuick import QQuickView
from PyQt5.QtQml import QQmlApplicationEngine

if __name__ == '__main__':

   app = QApplication(sys.argv)
   view = QQmlApplicationEngine('main_2.qml')
   #view.show()
   app.exec_()
   sys.exit()

import QtQuick 2.0
import QtQuick.Window 2.0
import QtWebEngine 1.0

Window {
    width: 1024
    height: 750
    visible: true
    WebEngineView {
        anchors.fill: parent
        url: "https://www.qt.io"
    }
}

但是我收到错误:

/usr/bin/python3 /home/unknown/IdeaProjects/new_ui/main.py QQmlApplicationEngine failed to load component file:///home/unknown/IdeaProjects/new_ui/main_2.qml:3 module "QtWebEngine" is not installed

自 PyQt 5.12 起，QtWebEngineWidgets 已被分离到另一个名为 PyQtWebEngine 的包中，所以你必须安装它:

python -m pip install PyQtWebEngine
