Use PyQt5.QtWebEngineWidgets on Windows: is it possible?

问题

I am trying to build an app in PyQt5 (version 5.6+) in Python 3.6. It contains a web browser, using QtWebEngineWidgets. It works fine on Mac, however, there are problems on Windows. When I run the code on Windows and import the module:

from PyQt5 import QtWebEngineWidgets

I get the following error:

ImportError: cannot import name 'QtWebEngineWidgets'

Now, reading some forums it looks like PyQt5.QtWebEngineWidgets is not available for Windows, yet. Is it correct? How can I have a web browser window, then?

I found online I could use QtWebKit, but according to here it seems QtWebKit was removed in Qt5.6. So what? Do I have to downgrade PyQt version?

I can't go under 5.6 in Python 3.6 anyway. Do I have to change Python version as well?

回答1:

you can try one of these solution ,

install old version :

pip install PyQt5==5.11.3

or install :

pip install PyQtWebEngine

回答2:

u can download PyQt5.6 from here: https://sourceforge.net/projects/pyqt/files/PyQt5/PyQt-5.6

QtWebKit got deprecated upstream in Qt 5.5 and removed in 5.6. Beacuse The QtWebEngineWidgets module is better than QtWebkit.

The example directory has many examples about QtWebEngineWidgets
