Python PyQt5 cannot import name 'QWebView'

Question

I keep getting this error:

ImportError: cannot import name 'QWebView'

...for this bit of code:

import sys
from PyQt5.QtCore import QUrl
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebPage

-I'm on a Mac running High Sierra 10.13.3
-I installed Python 3.6.4
-Installed PyQt5 (did this several times, including using HomeBrew)

I'm pretty sure everything is installed correctly cause when I run python3 -m pip install PyQt5 it tells me Requirement already satisfied :

MacBook-Pro-3:~ ericj36$ python3 -m pip install PyQt5
Requirement already satisfied: PyQt5 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages
Requirement already satisfied: sip<4.20,>=4.19.4 in /Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages (from PyQt5)

The full error I get when I try to run my code is:

 ...line 4, in <module>
    from PyQt5.QtWebEngineWidgets import QWebView
ImportError: cannot import name 'QWebView'

So what could be happening here? What am I doing wrong? (I'm new to Python - but not to development.)

Any help would be greatly appreciated.

There are two different web toolkits for Qt5: QtWebKit based on WebKit and the newer QtWebEngine based on Chromium.

Your imports seem to mix up those two. QWebPage and QWebView are part of QtWebKit , not of QtWebEngine , which has QWebEngineView and QWebEnginePage .

So you can choose either

• WebEngine :

   from PyQt5.QtWebEngineWidgets import QWebEnginePage from PyQt5.QtWebEngineWidgets import QWebEngineView 

• WebKit :

   from PyQt5.QtWebKitWidgets import QWebPage from PyQt5.QtWebKitWidgets import QWebView 

The interfaces of those two are largely compatible, but not exactly identical.
