You need to import Bootstrap in this way below:

from flask_bootstrap import Bootstrap
...
bootstrap = Bootstrap(app)

flask.ext.bootstrap is deprecated

The answer is correct.

You can test settings in the execution file, for example: flaskr/flaskr.py

from flask_bootstrap import Bootstrap
....
app = Flask(__name__)
bootstrap = Bootstrap(app)
db = SQLAlchemy(app)

The problem should have been solved.

By the time you posted the question, the import should be done as shown in the accepted answer, instead. – Billal Begueradj Sep 02 '17 at 08:31

If it's a full flask project, u need to do these:

from flask_bootstrap import Bootstrap
bootstrap = Bootstrap(app)

inside your __init__.py file
