jinja2.exceptions.TemplateNotFound: bootstrap/base.html

Question

I'm inheriting bootstrap/base.html in a Flask application after installing the Bootstrap Flask extension but having the below error:

jinja2.exceptions.TemplateNotFound: bootstrap/base.html

Answer 1

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.

Answer 2

You need to import Bootstrap in this way below:

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

flask.ext.bootstrap is deprecated
