Python (pip) - RequestsDependencyWarning: urllib3 (1.9.1) or chardet (2.3.0) doesn't match a supported version

This is because of different requests module installed by the OS and the python dependencies for your local installation.

It can be solved by upgrading requests:

pip install requests

or

pip3 install requests

You do have a mixed setup (both apt and pip were used to install system-wide, which is common), and it indeed doesn't match the supported versions of modules required by requests (and pip v1.5.6 is also quite old).

The requests (which version? likely leftover from pip install) requires:
urllib3: 1.21.1 - 1.22
chardet: 3.0.2 - 3.1.0

You have:
urllib3 (1.9.1) from python-urllib3 1.9.1-3 debian package
chardet (2.3.0) from python-chardet 2.3.0-1 debian package

Two options:

• either downgrade requests to the version from your OS distribution (see what's available with apt show python-requests), or older versions at pypi.org, or

• or install newer urllib3 and chardet (you can download the wheel files manually from pipy.org and do pip install on them, including any dependencies), either at user level (--user pip install option) or in a virtualenv.

You can test everything in a virtualenv (apt show python-virtualenv). It should even deploy a newer pip for you inside of its virtual envs. It is also possible to install a newer pip 10.0.1 at the user-level (--user) alongside your OS-vendored pip but you need to be careful about that. Good luck!

Faced similar error when upgraded to urllib3 1.23. Installation of older version 1.22 resolved this error for me.

Did following to install the older urllib3 version:

1. pip uninstall urllib3
2. pip install urllib3==1.22
