Unknown module(s) in QT: webenginewidgets

Question

Hi. I want to connect QtWebEngineWidgets. To do this, you need to write(https://doc.qt.io/qt-5/qtwebenginewidgets-module.html) in .cpp file

#include <QtWebEngineWidgets>

and

QT += webenginewidgets

inside .pro file.
The problem is that when writing to a .pro file, I get the error - Unknown module(s) in QT: webenginewidgets
Everywhere I read, it is only written that you need to connect the module in the .pro file, but it doesn’t work for me. Am I doing everything right?
• Qt Creator version - 5.0.0 Community
• Qt version - 6.1.3
• C++ compiler version - MSVC2019 64bit 17.032112.339(amd64)
UPD: I want to add that this module is not in the installer.
Installer exaple1, Installer example2

Answer 1

Possibly the needed files aren't installed. Try adding this package containing the development files:

sudo apt-get install qtwebengine5-dev

Answer 2

It turned out that it was necessary to install a newer version of Qt. For example, since version 6.2.3.0 and newer, the installer contains the "WebView" item. I'm installing it now and I'll see if it helps. Thank you.
