Bootstrap-Flask can't work together with Flask-Bootstrap, you have to uninstall them then reinstall Flask-Bootstrap:

$ pip uninstall bootstrap-flask flask-bootstrap
$ pip install flask-bootstrap

Sorry for the inconvenience, to follow Flask's extension development rule, I have to name the package of Bootstrap-Flask in a format like flask_xxx (i.e. flask_bootstrap), that's the same package name of Flask-Bootstrap. It's too late when I realize this conflict :(

I feel like a genius right now. clap for me please. I was able to solve this by uninstall bootstrap-flask and reinstalling the latest version of flask-bootstrap 3.3.7.1

It does work on Python 3.6.8, but it seems it broke on Python 3.7.x

Facing the same issue using Python 3.7.x. Were you able to solve this error @nmaas87 on 3.7.x

[nmaas87]
