flask-appbuilder dependency out of date for Python3

[EricSchles]

Hello all,

I received the following error:

Was unable to import caravel Error: make_declarative_base() takes 1 positional argument but 2 were given

Until I did:

sudo pip3 install flask-appbuilder

which resolved things.

I'd strongly recommend using virutalenv. From seeing that sudo I'm guessing your python environment has some conflicting versions/ incompatible history.

Python fails at managing "diamond dependencies" (when 2 different packages need different version of a the same package). Knowing this, it makes a lot of sense to use virtualenv to keep insulated Python environment for each project.
