python - Python3:ImportError:/lib/x86_64-linux-gnu/libQt5Core.so.5:未找到版本“Qt_5.15”
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 - 我得到 ImportError。感觉就像那个库没有安装在我的系统中。但预览在 Qt Designer 中有效。

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 包是通过 pip 安装的。
解决方案
我尝试卸载pyqt5重新安装,还是有用的!</p>
在 pycharm 终端中:
pip3 uninstall PyQt5
在 ubuntu 终端中:
sudo apt-get install python3-pyqt5
