问题描述

我使用Qt Designer在Qt上创建了一个窗口，当我启动该应用程序时-我收到ImportError。感觉该库未安装在我的系统中。但是预览可以在Qt Designer中使用。

设计文件的完整代码：

# -*- coding: utf-8 -*-

# Form implementation generated from reading ui file 'map.ui'

from PyQt5 import QtCore,QtGui,QtWidgets


class Ui_Form(object):
    def setupUi(self,Form):
        Form.setobjectName("Form")
        Form.resize(576,616)
        self.horizontalLayout = QtWidgets.QHBoxLayout(Form)
        self.horizontalLayout.setobjectName("horizontalLayout")
        self.webView = QtWebEngineWidgets.QWebView(Form)
        self.webView.setUrl(QtCore.QUrl("https://www.openstreetmap.org/"))
        self.webView.setRenderHints(QtGui.QPainter.Antialiasing|QtGui.QPainter.SmoothpixmapTransform|QtGui.QPainter.TextAntialiasing)
        self.webView.setobjectName("webView")
        self.horizontalLayout.addWidget(self.webView)

        self.retranslateUi(Form)
        QtCore.QMetaObject.connectSlotsByName(Form)

    def retranslateUi(self,Form):
        _translate = QtCore.QCoreApplication.translate
        Form.setwindowTitle(_translate("Form","VasMaps"))
        
from PyQt5 import QtWebEngineWidgets

错误日志：

Traceback (most recent call last):
  File "Qt/map.py",line 31,in <module>
    from PyQt5 import QtWebEngineWidgets
ImportError: /lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by /usr/local/lib/python3.8/dist-packages/PyQt5/QtWebEngineWidgets.abi3.so)

PyQtWebEngine软件包是通过pip安装的。

解决方法

尝试卸载pyqt5重新安装，有用！

在pycharm终端中：

pip3 uninstall PyQt5

在 ubuntu 终端中：

sudo apt-get install python3-pyqt5
