PyQt5模块"QtQuick"未安装 [英] PyQt5 module "QtQuick" is not installed

问题描述

我正在尝试使用Windows或Linux获得一个基本的PyQt5 QML项目.我首先尝试过Linux，但现在运气不佳，我正在尝试Windows.我的问题是，每当我尝试通过python main.py运行它时，都会抱怨未安装模块"QtQuick"和未安装模块" QtQuick.Window.

I'm trying to get a basic PyQt5 QML project going using either Windows or Linux. I first tried Linux and with no luck am trying Windows now. My issue is whenever I try and run it via python main.py it will complain that "module "QtQuick" is not installed" and "module "QtQuick.Window" is not installed".

我觉得这只是指向QT安装位置的一些简单路径，但不知道从这里到哪里.使用Qt窗口小部件有效，但不能使用QML.

I feel like this is a simple pointing of some path to the QT install location but don't know where to go from here. Using Qt Widgets works but not QML.

我的main.py文件是:

My main.py file is:

import sys

from PyQt5.QtQml import QQmlApplicationEngine
from PyQt5.QtGui import QGuiApplication

def _find_plugins():
    import PyQt5
    from os import path
    paths = [path.abspath(path.join(path.dirname(PyQt5.__file__), 'plugins'))]
    import PyQt5.QtCore
    PyQt5.QtCore.QCoreApplication.setLibraryPaths(paths)

if __name__ == '__main__':
    # _find_plugins()

    app = QGuiApplication(sys.argv)

    engine = QQmlApplicationEngine()

    engine.load('test.qml')

    sys.exit(app.exec_())

我的test.qml文件是:

and my test.qml file is:

import QtQuick 2.2
import QtQuick.Window 2.1

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    minimumWidth: 400
    minimumHeight: 300
}

推荐答案

原来，我需要添加以下环境变量:

Turns out I needed to add the following Environment Variable:

QML2_IMPORT_PATH

在我的情况下，值为:

C:\Python35\Lib\site-packages\PyQt5\qml
