SSL InsecurePlatform error when using Requests package

by

Use the somewhat hidden security feature:

pip install requests[security]
or
pip install pyOpenSSL ndg-httpsclient pyasn1

Both commands install following extra packages:

  • pyOpenSSL
  • cryptography
  • idna

Please note that this is not required for python-2.7.9+.

If pip install fails with errors, check whether you have required development packages for libffi, libssl and python installed in your system using distribution’s package manager:

  • Debian/Ubuntu – python-dev libffi-dev libssl-dev packages.

  • Fedora – openssl-devel python-devel libffi-devel packages.

Distro list above is incomplete.

Workaround (see the original answer by @TomDotTom):

In case you cannot install some of the required development packages, there’s also an option to disable that warning:

import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()

If your pip itself is affected by InsecurePlatformWarning and cannot install anything from PyPI, it can be fixed with this step-by-step guide to deploy extra python packages manually.
