libQt5MultimediaQuick.so.5: 无法打开共享对象文件：没有那个文件或目录

Question

我正在做一个名为 RaspMedia 的项目（我的项目文件夹的名称也是那个）。我使用 PyQt5 将 QML 和 python 组合在一起。

我尝试在我的 main.qml 文件中使用导入语句 import QtMutimedia 5.14 导入 QtMultimedia。

这是我的完整 python 代码。

main.py

from PyQt5.QtCore import QObject, QUrl,QMimeDatabase,QVariant,QFileInfo,QMetaObject,Q_ARG
from PyQt5.QtWidgets import QApplication
from PyQt5.QtQml import QQmlApplicationEngine
import os
import sys
home = os.environ["HOME"]+"/"
print(home)
currentPath = home

def getList(directory:type=str):
    a = os.popen("ls '"+directory+"'")
    b = []
    for i in a:
        b.append(i.replace("\n", ""))
    return b

def appendToList(mainList:type=list):
    for i in mainList:
        path = currentPath + i
        mime = QMimeDatabase().mimeTypeForFile(QFileInfo(path)).name()
        if mime == "inode/directory":
            anObject = {"type":"folder", "name":i, "path":path }
            QMetaObject.invokeMethod(win, "append", Q_ARG(QVariant, anObject))
            print(anObject)

DIR_PATH = os.path.dirname(os.path.realpath(__file__))
if __name__ == '__main__':
    file = os.path.join(DIR_PATH, "main.qml")
    url = QUrl.fromLocalFile(file)
    myApp = QApplication(sys.argv)

    engine = QQmlApplicationEngine()
    context = engine.rootContext()
    context.setContextProperty("main", engine)


    engine.load(url)

    win = engine.rootObjects()[0]
    appendToList(getList(home))

    win.show()

    sys.exit(myApp.exec_())

运行它给了我下面的错误

file:///home/newtron/RaspMedia/main.qml:5:1: plugin cannot be loaded for module "QtMultimedia": Cannot load library /usr/local/lib/python3.6/dist-packages/PyQt5/Qt/qml/QtMultimedia/libdeclarative_multimedia.so: (libQt5MultimediaQuick.so.5: cannot open shared object file: No such file or directory)

同方pyside顺利运行脚本无任何错误

这是ldd /usr/local/lib/python3.6/dist-packages/PyQt5/Qt/qml/QtMultimedia/libdeclarative_multimedia.so

Qt version:5.14.1
Python version:3.6
os: Ubuntu 18.04

Answer 1

我想出了解决办法。 PyQt5 的 MultiMediaQuick 包有错误。所以我复制并粘贴了

Qt5.14.1/5.14.1/gcc_64/lib/libQt5MultimediaQuick.la
Qt5.14.1/5.14.1/gcc_64/lib/libQt5MultimediaQuick.so
Qt5.14.1/5.14.1/gcc_64/lib/libQt5MultimediaQuick.prl
Qt5.14.1/5.14.1/gcc_64/lib/libQt5Multimedia.so.5.14.1
Qt5.14.1/5.14.1/gcc_64/lib/libQt5MultimediaQuick.so.5 文件到 /usr/local/lib/python3.6/dist-packages/PyQt5/Qt/ 和一些附加文件，例如 gstreamer 和包含文件夹。现在完美了。

libQt5MultimediaQuick.so.5: 无法打开共享对象文件：没有那个文件或目录

libQt5MultimediaQuick.so.5: cannot open shared object file: No such file or directory

python-3.x

qml

pyqt5
