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

Solution 1

You need to import Bootstrap in this way below:

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

flask.ext.bootstrap is deprecated

Solution 2

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.

Solution 3

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

Solution 4

Need to import Bootstrap from flask.ext.bootstrap and bootstrap the flask app as below:

from flask.ext.bootstrap import Bootstrap
...
bootstrap = Bootstrap(app)
