ImportError: cannot import name 'parse_rule' from 'werkzeug.routing' - Troubleshooting Guide

This error occurs when the 'parse_rule' function cannot be imported from the 'werkzeug.routing' module.

This could be due to a few reasons:

1. Outdated version of Werkzeug: The 'parse_rule' function might not be available in the version of Werkzeug you are using. Try updating Werkzeug to the latest version.

2. Incorrect import statement: Double-check your import statement to ensure it is correct. It should be 'from werkzeug.routing import parse_rule'.

3. Corrupted or missing installation: It's possible that your Werkzeug installation is corrupted or missing some files. In this case, you can try reinstalling Werkzeug using 'pip install werkzeug'.

If none of these solutions work, you may need to provide more information about your code and the specific version of Werkzeug you are using for further assistance.
