Not able to deploy site anymore

Hi, I installed a couple of modules and now my site is not working. I get the following error. This happened after upgrading setuptools I believe.

It looks like you've upgraded werkzeug to a version that isn't compatible with the version of flask_httpauth that you're using; the function safe_str_cmp was removed from werkzeug recently, according to this post. You should find out if there's a more recent flask_httpauth that is compatible with newer versions of werkzeug, or downgrade werkzeug to a version that's compatible with flask_httpauth (it looks like that would be whatever version came before 2.1.0).
