Introduction to the Problem

Are you encountering the frustrating ImportError: DLL load failed while importing QtWebKit: Le module spécifié est introuvable while trying to run your PyQt5 application? You're not alone! This is a common issue among developers who are working with PyQt5 and are trying to integrate web functionalities into their applications.

In this guide, we'll go through what this error means and how to effectively resolve it by switching from QtWebKit to Qt WebEngine, ensuring your application runs smoothly.

Understanding the Error

The error message indicates that the module QtWebKit could not be found or loaded properly, which often happens for several reasons:

The library might not be installed on your system.

There might be a version mismatch between the PyQt version you are using and the libraries installed.

You are attempting to use QtWebKit, which is deprecated in favor of Qt WebEngine.

The code snippet you provided is trying to import QWebSettings and QWebView from QtWebKit, which leads to the ImportError.

Solution to the Problem

To fix this issue, it is recommended to use Qt WebEngine, which is the modern replacement for QtWebKit. Let's go through the steps together.

Step 1: Install the Required Libraries
