Error when Trying to Deploy Flask App to AWS Elastic Beanstalk

I am trying to deploy a Flask application using AWS Elastic Beanstalk and unfortunately have run into the following error. What confuses me is that the current version of pip in my virtual environment and local machine is 9.0.1, so I am not sure why it is picking up 7.1.2.

Command "/opt/python/run/venv/bin/python2.7 -c "import setuptools, tokenize;__file__='/tmp/pip-build-L32BGc/cffi/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" install --record /tmp/pip-nO55i_-record/install-record.txt --single-version-externally-managed --compile --install-headers /opt/python/run/venv/include/site/python2.7/cffi" failed with error code 1 in /tmp/pip-build-L32BGc/cffi
  You are using pip version 7.1.2, however version 9.0.1 is available.
  You should consider upgrading via the 'pip install --upgrade pip' command.

This is because the pip version is too old. you can add .ebextensions to solve this.

  1. add .ebextensions folder in the root folder of your app
  2. put a pip.config file inside it, the content is :

commands:
  update_pip:
  command: "/opt/python/run/venv/bin/pip install --upgrade pip"
  1. run eb deploy again, it will be resolved.
