ImportError: cannot import name 'Markup' from 'jinja2'

How to deal with it？

[NanmiCoder]

The reason for this error is that the Flask version in the requirements file of the project is not consistent with the Jinja2 version. Uninstall Flask and then install it again.

pip uninstall flask
pip install flask
