Module QtQuick is not installed (PyQt5)

[Grut]

Hi. I have a problem.
I try to run simple script from tutorial.

import sys
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQuick import QQuickView

# Main Function
if __name__ == '__main__':
    # Create main app
    myApp = QApplication(sys.argv)
    # Create a label and set its properties
    appLabel = QQuickView()
    appLabel.setSource(QUrl('basic.qml'))

    # Show the Label
    appLabel.show()

    # Execute the Application and Exit
    myApp.exec_()
    sys.exit()

vs simple qml code

import QtQuick 2.0

Rectangle {
    width: 250; height: 175

    Text {
        id: helloText
        anchors.verticalCenter: parent.verticalCenter
        anchors.horizontalCenter: parent.horizontalCenter
        text: "Hello World!!!\n Traditional first app using PyQt5"
        horizontalAlignment: Text.AlignHCenter
    }
}

When i run code, Python showing mistake.
'Module "QtQuick" is not installed'

I use pyqt5 and virtualenv on ubuntu.
python-pyqt5.qtquick was installed.

Two additional question.
How to print in console(or window) version of module (and qml too)?
How to point in python-script way to library

Can anybody help me?
