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-devlibffi-devlibssl-devpackages. -
Fedora –
openssl-develpython-devellibffi-develpackages.
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.
