I solved this issue with the following: sudo pip install --upgrade pip Ubuntu/Debian’s default version of pip will alter sys.path and thus force requests and urllib3 down to older versions. Docker compose uses pip on startup to detect if old versions are installed.

This was actually on Bash on Ubuntu for Windows.

Had the same problem with

• ubuntu 14.04
• docker 1.12.1
• docker-py==1.8.1
• urllib3==1.7.1

Solved it by

pip install urllib3==1.14

and

export PYTHONPATH=/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages
