Error: make_declarative_base() takes exactly 1 argument (2 given) about superset HOT 6 CLOSED

Looks like for some reason, installing caravel from scratch using pip installs the wrong version of flask-sqlalchemy.

I found this bug on the Flask-AppBuilder project referencing the same error. Even though caravel has flask-sqlalchemy pinned at 2.0, 2.1 got installed for me.

You can work around it by installing flask-sqlalchemy v2.0 first:

pip uninstall flask-sqlalchemy
pip install flask-sqlalchemy==2.0

After doing that, the create-admin step worked fine.

note: I'm using a virtualenv specifically for caravel and python 2.7

Diamond dependencies? I've seen that bug before too. I'm not sure where the 2.1 gets picked up from. I didn't see it when digging in using the pipdeptree utility

from superset.

I have no way of testing things on windows though, so I'm surprised it even works. I think Travis (our build system) can do windows build. It would be nice if someone added windows to the build matrix.

My build was on Ubuntu 14.04.4 LTS, experienced the same issue.
