QWebEngineView找不到已安装的某些库

Question

为了解决显示问题，建议我使用QWebEngineView。我插入from PyQt5.QtWebEngineWidgets import QWebEngineView在执行时发出的脚本中：

from PyQt5.QtWebEngineWidgets import QWebEngineView
ImportError: libQt5Positioning.so.5: cannot open shared object file: No such file or directory

我使用python3.8而不使用venv。如果我使用venv，它甚至找不到QtWebEngineWidgets

通过Pycharm，我通过将PyQtWebEngine从5.12更新到5.15 来解决问题
