QML 图形效果不适用于 PyInstaller

Question

当我使用 PyInstaller 4.1 捆绑我的 PySide2 QML 应用程序时。不会呈现任何图形效果。我在下面有一个 LinearGradient 不起作用的示例。

main.qml

import sys
import os

from PySide2.QtGui import QGuiApplication
from PySide2.QtQml import QQmlApplicationEngine


if __name__ == "__main__":
    app = QGuiApplication(sys.argv)
    engine = QQmlApplicationEngine()
    engine.load(os.path.join(os.path.dirname(__file__), "main.qml"))

    if not engine.rootObjects():
        sys.exit(-1)
    sys.exit(app.exec_())

main.py

import QtQuick 2.15
import QtQuick.Window 2.15
import QtGraphicalEffects 1.15

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    Item {
        width: 300
        height: 300

        LinearGradient {
            anchors.fill: parent
            start: Qt.point(0, 0)
            end: Qt.point(0, 300)
            gradient: Gradient {
                GradientStop { position: 0.0; color: "white" }
                GradientStop { position: 1.0; color: "black" }
            }
        }
    }
}

当我运行这个简单的 pyinstaller 命令成功时，没有任何错误：

这是 /dist 中所有文件和目录的列表： https://pastebin.com/raw/2XMmi2yi

以下是运行应用 QT_DEBUG_PLUGINS=1 后的输出： https://pastebin.com/raw/fHG1th1u

我已经尝试在两个不同的系统上执行此操作，结果相同。

此问题已在 PyInstaller 中得到解决。我提交了错误，开发人员修复了它。
