我正在做一个名为RaspMedia的项目(我的项目文件夹也就是这个名字(。我使用PyQt5将QML和python组合在一起。
我已经尝试使用main.qml文件中的import语句import QtMutimedia 5.14导入QtMultedia。
这是我完整的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_())
运行它给了我错误跟随
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)
在同一方面，pyside顺利地运行了脚本，没有任何错误。
这是ldd /usr/local/lib/python3.6/dist-packages/PyQt5/Qt/qml/QtMultimedia/libdeclarative_multimedia.so的完整输出

软件信息
- PyQt版本：5.14.1
- Qt版本：5.14.1
- Python版本：3.6
- os:Ubuntu2004年18月
我想好了如何修复它。PyQt5在MultiMediaQuick包中有一个错误。所以我复制粘贴了
- Qt5.14.1/5.1/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/和一些额外的文件，如gstreamer和include文件夹。现在它工作得很好
