It has been moved to a separated package.
它已移至单独的包中。
Based on this answerand my own experience, Just execute in a terminal:
根据这个答案和我自己的经验，只需在终端中执行：
pip install PyQtWebEngine
If you still got problems with PyQt, try uninstalling all of the PyQt related libraries:
如果您仍然遇到 PyQt 问题，请尝试卸载所有 PyQt 相关库：
pip uninstall PyQt5
pip uninstall PyQt5-sip
pip uninstall PyQtWebEngine
Then install them again, which should fix the following errors:
然后再次安装它们，这应该修复以下错误：
ModuleNotFoundError: No module named 'PyQt5.sip'
ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets'
If you got problems uninstalling the libraries, go to your Python folder, like C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python<PYTHON-VERSION>\Lib\site-packagesand manually delete the PyQt folders, then uninstall everything and install again. (Make sure you have the latest Python version and upgraded your pip too.)
如果您在卸载库时遇到问题，请转到您的 Python 文件夹，例如C:\Users\<USERNAME>\AppData\Local\Programs\Python\Python<PYTHON-VERSION>\Lib\site-packages并手动删除 PyQt 文件夹，然后卸载所有内容并重新安装。（确保您拥有最新的 Python 版本并升级了您的 pip。）

For me, first uninstallingPyQtWebEngine with
pip uninstall PyQtWebEngineand then reinstallingwith
pip install PyQtWebEnginesolved the problem of Spyder not starting.
对我来说，先卸载PyQtWebEngine与
pip uninstall PyQtWebEngine和再重新安装以
pip install PyQtWebEngine解决Spyder的问题无法启动。
