According to Jinja project, escape and markup should be imported from MarkupSafe. These functions are removed from jinja version 3.1.0.
If you are using jinja version <3.1.0 or flask version <V2, then you will get ImportError: cannot import name ‘escape’ or ‘markup’ from ‘jinja2’.
Solution
The solution to this issue is to either downgrade jinja to match compatible version of Flask, or upgrade Flask to version 2+.
Open your requirements.txt file and add this to the end of file –
Flask==2.1.0
Or, you can use MarkupSafe package –
>>> from jinja2.utils import markupsafe >>> markupsafe.Markup()
Or, you can also upgrade all the libraries listed in requirements.txt file –
pip install --upgrade <requirements.txt>
Conclusion
Flask has a dependency on jinja and that’s why you are getting this error. A simple upgrade will be enough to resolve it.
