无法在Python3中导入QtWebEngineWidgets

Question

I'm currently developing a web browser in Python using Qt5. However, when I try to run it, I get the following:

ImportError: No module named QtWebEngineWidgets

What this error is referring to is one of the import statements in my code:

from PyQt5.QtWebEngineWidgets import QWebView

If anyone could help me here, it'd be much appreciated.

Seems like the package "python-pyqt5.qtwebengine" doesn't exist in the Raspbian (the OS I'm running on my RPi) repositories, but it does exist in the Debian Sid repositories. I had to add the Debian Sid mirror to my /etc/apt/sources.list, and then run the following commands to make my system "trust" the Debian repositories:

gpg -a --export 04EE7237B7D453EC | sudo apt-key add -
gpg -a --export 7638D0442B90D010 | sudo apt-key add -

Then I did sudo apt update, and then sudo apt install python-pyqt5.qtwebengine. It's installing right now. After it has finished installing, I will remove the Debian Sid repositories.
