 This is because of using https instead of http

It is because the dependency is not fulfilled in elastic bean. So using ec2, i created my own ubuntu and install the dependency below:    sudo apt-get install python-dev default-libmysqlclient-dev libssl-dev then: pip install --user flask-mysqldb

  python3 -m pip install --user virtualenv create virtual env: python3 -m venv env activate the env: source env/bin/activate check: which python install from requirements file pip install -r requirements.txt

enter into database with: sudo mysql -u root and type:   GRANT ALL PRIVILEGES ON *.* TO 'puri'@'%';
