PyInstaller + PyQt5 + QML: QtQuick is not installed

问题

I'm trying to build an app using pyinstaller, PyQt5 and qml (see files below) using the following command.

pyrcc5 pyqt5_qml.qrc > pyqt5_qml_qrc.py
pyinstaller -w -F --noupx pyqt5_qml.py

(OSX 10.11.1, python 3.5.0, qt 5.5.1, pyinstaller 3.0)

The pyqt5_qml.py runs fine (open an "Hello world!" window) but the built app complains about module "QtQuick" version 2.4 is not installed. I guess the module has not been included into the built app but I'm not sure how to tell pyinstaller to do it.

pyqt5_qml.py:

import os, sys
from PyQt5 import QtCore, QtWidgets, QtQml
import pyqt5_qml_qrc

def main():
    global app 
    app = QtWidgets.QApplication(sys.argv)
    engine = QtQml.QQmlApplicationEngine()
    engine.load(QtCore.QUrl('qrc:/hello.qml'))
    root = engine.rootObjects()[0]
    root.show()
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

hello.qml:

import QtQuick 2.4
import QtQuick.Controls 1.3
import QtQuick.Layouts 1.1

ApplicationWindow {
    title: qsTr("Window")
    Rectangle {
        width: 360
        height: 360
        Text {
            anchors.centerIn: parent
            text: "Hello World"
        }
        MouseArea {
            anchors.fill: parent
            onClicked: {
                Qt.quit();
            }
        }
    }
}

pyqt5_qml.qrc:

<!DOCTYPE RCC><RCC version="1.0">
<qresource>
    <file>hello.qml</file>
</qresource>
</RCC>

回答1:

For me it on Windows this ended up being the QML2_IMPORT_PATH environment variable had not been set. Once I set this to "C:\Python35\Lib\site-packages\PyQt5\qml" it worked!

Working with PyInstaller I've noticed that it simply fails to bundle QML dependencies then freezing an app. You can check whether it is your case as well by copying QtQuick and QtQuick.2 folders from python site packages (<your_python_path>\Lib\site-packages\PyQt5\Qt\qml) and placing it near freezed executable:

QtQuick
QtQuick.2
your_executable.exe

If app works after this, you can edit .spec file to bundle these folders automatically (pyinstaller generate .spec-file on first run).

# -*- mode: python -*-
import os
import site

block_cipher = None

site_packages_dir = site.getsitepackages()[1]
qml_dir = os.path.join(site_packages_dir, 'PyQt5', 'Qt', 'qml')

added_files = [
    (os.path.join(qml_dir, 'QtQuick'), 'QtQuick'),
    (os.path.join(qml_dir, 'QtQuick.2'), 'QtQuick.2'),
]

a = Analysis(['pyqt5_qml.py'],
             binaries=None,
             datas=added_files,
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data, cipher=block_cipher)

exe = EXE(pyz,
          a.scripts,
          exclude_binaries=True,
          name='app',
          debug=False,
          strip=False,
          upx=False,
          console=True,
)

coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=False,
               name='pyqt5_qml')

Then try to run pyinstaller against this spec-file: pyinstaller pyqt5_qml.spec
