[MajedAlghoul]

Description

the script fails to launch due to werkzeug version incompatibility with flask.

How to reproduce

1. run requirements.txt without having werkzeug already installed
2. run main.py

Error Details

Traceback (most recent call last):
  File "pdf-to-audiobook-converter\main.py", line 4, in <module>
    from flask import Flask, render_template, send_file
  File "Python\Python312\Lib\site-packages\flask\__init__.py", line 5, in <module>
    from .app import Flask as Flask
  File "Python\Python312\Lib\site-packages\flask\app.py", line 30, in <module>
    from werkzeug.urls import url_quote
ImportError: cannot import name 'url_quote' from 'werkzeug.urls' (Python\Python312\Lib\site-packages\werkzeug\urls.py). Did you mean: 'unquote'?

Explaination and Solution

the issue is most likely that since the version of werkzeug is not specified in the requierments.txt file, the latest version gets installed which is not compatible with flask, at least version 2.2.3.

a possible solution is adding this line to the requierments.txt file:

Werkzeug==2.2.2
