Docker-compose start fail

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

1. copy the newest urllib3 into requests/packages

2. 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'>

)
