ERROR: Failure: ModuleNotFoundError (No module named 'flask_sqlalchemy')

Question

from flask import Flask, request, jsonify, make_response
import json
from flask_sqlalchemy import SQLAlchemy
from datetime import datetime

I have the import options in my app.py as above, the code runs well on my local machine but I get this error during travis build:

    Traceback (most recent call last):
