Description:

Currently, importing QtQuick 2.10 and QtQuick.Controls 2.2 fails.
However, importing lower verison e.g. QtQuick 2.9, 2.8...etc. works fine.

Additional info:
* package version(s): python-pyqt5 5.10.1-3


Steps to reproduce:

import QtQuick 2.10
import QtQuick.Controls 2.3

in a QML file and


engine = QQmlApplicationEngine()
engine.load(QUrl(QML_PATH))

fails in a python file.

Typo. I meant importing importing QtQuick 2.10 and QtQuick.Controls 2.3.

Please post full qml and py files that fail.
Comment by Bumsik Kim (kbumsik) - Wednesday, 13 June 2018, 08:27 GMT
Sure. This is a simple script that loads a QML file.
I get message like this:

QQmlApplicationEngine failed to load component
file:///home/kbumsik/project/BuggyWindow.qml:1 module "QtQuick" version 2.10 is not installed

Switing to

import QtQuick 2.9
import QtQuick.Controls 2.2

in BuggyWindow.qml works fine.
   pyqt_bug.py (0.5 KiB)
   BuggyWindow.qml (0.2 KiB)

Which version of qt5-declarative? Also, output of "echo $QML2_IMPORT_PATH"?

> Which version of qt5-declarative?
It's 5.11.0-1.

> output of "echo $QML2_IMPORT_PATH"?
It outputs nothing. So QML2_IMPORT_PATH is not set in env.

Please post the output of 'QML_IMPORT_TRACE=1 qmlscene BuggyWindow.qml'

Oh, I figured out why. It's my bad. Installing Anaconda (AUR) causes PyQt to look at /opt/anaconda/qml first. I'm not sure how Anaconda can do this though. It's not even in $PATH.

qmlscene looks up correct path /usr/lib/qt/qml:

But PyQt looks up Anaconda path:

QQmlImportDatabase::addImportPath: "qrc:/qt-project.org/imports"

QQmlImportDatabase::registerPluginTypes: "QtQuick" from "/opt/anaconda/qml/QtQuick.2"
QQmlApplicationEngine failed to load component
file:///home/kbumsik/project/BuggyWindow.qml:1 module "QtQuick" version 2.10 is not installed


Anyway, thank you for your time.
