Python 3.7.0 No module named 'PyQt5.QtWebEngineWidgets'

Question

I have Python 3.7.0 and I installed PyQt5 with this command:

pip install PyQt5 

I have returned this error:

    main.py", line 4, in <module>     from PyQt5.QtWebEngineWidgets import * ModuleNotFoundError: No module named 'PyQt5.QtWebEngineWidgets' 

In Eclipse I have this configuration:

What may be wrong?

Answer 1

It has been moved to a separated package.

Based on this answer and my own experience, Just execute in a terminal:

pip install PyQtWebEngine 

If you still got problems with PyQt, try uninstalling all of the PyQt related libraries:

pip uninstall PyQt5 pip uninstall PyQt5-sip pip uninstall PyQtWebEngine 

Then install them again, which should fix the following errors:

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-packages 

and manually delete the PyQt folders, then uninstall everything and install again.

Make sure you have the latest Python version and upgraded your pip too

For me, first uninstalling PyQtWebEngine with pip uninstall PyQtWebEngine and then reinstalling with pip install PyQtWebEngine solved the problem of Spyder not starting.
