I deployed my flask application into aws beanstalk and ran into an import error:

ImportError: No module named flask.ext.sqlalchemy

In my application.py file, I have this statement 

from flask.ext.sqlalchemy import SQLAlchemy

and it runs fine on my machine but does not work in aws elastic beanstalk.

Anyone ran into a similar issue?

Make sure you have included a requirements.txt file in root directory of your project.

The file should include any pip package that needs to be installed

Flask-SQLAlchemy=1.0
