Quick Fix: Flask has deprecated the ‘Markup’ feature. Utilize the HTMLString class or render_template() to format strings for HTML display.
The Problem:
You installed a new Flask version, and you’re trying to import the Markup class from the flask module, but it’s not available in the current version of Flask. You want to import the Markup class without having to reinstall Flask.
The Solutions:
Solution 1: Uninstall and install an older version of Flask
If the error is “ImportError: cannot import name ‘Markup’ from ‘flask'”, you should try uninstalling the current version of Flask and reinstalling an older version. This is because recent versions of Flask have sunset flask.Markup, and you are using an older version of the library that still requires it.
To install an older version of Flask, you can use the pip command:
pip install flask==2.3.1
This will install Flask version 2.3.1, which is a version that still includes the Markup class.
Once you have installed an older version of Flask, you may need to remove the line ‘from markupsafe import Markup’ from your code. This line is no longer necessary in newer versions of Flask, and it may be causing the import error.
