I am trying to run my app, getting an error

ImportError: cannot import name 'import_string' from 'werkzeug'

The error is from

venv/lib/python3.7/site-packages/flask_cache/__init__.py", line 24, in <module>
    from werkzeug import import_string

I am running Python 3.7

pip freeze says
Werkzeug==1.0.1
Flask==1.1.1
Flask-Cache==0.13.1
redis==3.5.3

Anyone else run into this error? Anyone know of a fix?

For anyone stumbling into this issue, here is the quick'n dirty way to solve this:

# Monkeypatch to fix import in flask-cache
from werkzeug.utils import import_string
import werkzeug
werkzeug.import_string = import_string

import flask_cache  # Obviously flask_cache must be imported after the monkeypatch
