Getting error 'ConnectionError: ('Connection aborted.', error(2, 'No such file or directory'))'

See original GitHub issue

I am getting an error when trying to use dockerpty. Using the example in the README:

import docker
import dockerpty

client = docker.Client()
container = client.create_container(
    'busybox:latest',
    stdin_open=True,
    tty=True,
    command='/bin/sh')

dockerpty.start(client, container)

When I run this, I get the error:

Traceback (most recent call last):
  File "test_script.py", line 9, in <module>
    command='/bin/sh')
  File "/Users/michaelbarton/Library/Python/2.7/lib/python/site-packages/docker/api/container.py", line 116, in create_container

If you’re using Docker Machine, you can point docker-py at it using docker-machine env and the kwargs_from_env() utility method.

from docker import Client
from docker.utils import kwargs_from_env

client = Client(**kwargs_from_env(assert_hostname=False))
...

$ eval "$(docker-machine env default)"
$ python script.py

@michaelbarton @mejamiewilson Did you find any solution ? I understand that eval ${docker-machine env default} works great for command, but any solution for Client() via script ?
