Eve 1.0 crashes with Werkzeug 1.0.0

[gwainer]

Expected Behavior

Using python 3.7.6, eve 1.0 crashed on app startup, apparently due to werkzeug 1.0.0. By using werkzeug 0.16 the error does not happen.

from eve import Eve

Actual Behavior

Below is the error traceback.

Thanks for reporting this. They released 1.0 yesterday. To be fair, they had deprecation warnings in place since 0.16 (I think), and we only partially complied.

@nicolaiarocci Issue seems to persist but with different method.

Environment:

Python 3.7.6
Eve 1.1

Installed dependencies:

setuptools==41.0.1
flask-pymongo==0.5.2
redis==2.10.6
requests-oauthlib==1.1.0
eve==1.1
eve-swagger==0.0.11
Werkzeug==1.0.0
uwsgi==2.0.18
flask-cors==3.0.8
flask-sentinel==0.0.7

ImportError: cannot import name 'cached_property' from 'werkzeug' (/usr/local/lib/python3.7/site-packages/werkzeug/__init__.py)

As of now, I can only get Eve==1.1 to work with Werkzeug==0.16.1 only.

by looking at the stack I would say tat this is a flask_sentinel issue, please open a ticket over there. Thanks!
