Docker-compose start fail - docker

Question

I am trying to install and use docker-compose for the first time on my Ubuntu 14.04 machine, but I am failing :))
I have installed docker-compose via pip using
When I try to run docker-compose up I get this error trace:
Traceback (most recent call last):

urllib3.connection.match_hostname = match_hostname
AttributeError: 'module' object has no attribute 'connection'
Eggs versions:
$pip freeze | grep -e urllib3 -e requests -e docker-py
docker-pycreds==0.2.1
requests==2.13.0
urllib3==1.14
I tried to export PYTHONPATH like this:
export PYTHONPATH=/usr/local/lib/python2.7/dist-packages:/usr/lib/python2.7/dist-packages

I guess you have more than one packages with different version.
request and urllib3 can both exist in /usr/lib/python2.7/dist-packages/ and /usr/local/lib/python2.7/dist-packages
In ssladapter.py, request.packages.urllib3 is priorly imported according:
try:
import requests.packages.urllib3 as urllib3
except ImportError:
import urllib3
If your requests.packages.urllib3 is too old, error will be raised.
So you have two ways to fix this problem
copy the newest urllib3 into requests/packages
remove the urllib3 in requests/packages so that docker-compose will use the urllib3 from pythonpath (your latest urllib3)
(You can get the path of requests by the interactive console:
>>> import requests
>>> requests
<module 'requests' from '/usr/lib/python2.7/dist-packages/requests/__init__.pyc'>
)
