  <p>According to the my error message and <a href="https://urllib3.readthedocs.org/en/latest/security.html#insecureplatformwarning" rel="nofollow noreferrer">urllib3</a> my problem is because I have a python installation version earlier than earlier than 2.7.9 but my python is 2.7.10 as you can see</p>

  <p>I verified my openssl installed and it seems to be ok</p>

  <p>not sure how to fix this, any idea ?</p>
