sudo pip install --upgrade docker-compose fixes it

[MrMMorris]

I guess I'll leave it open in case you need to do something on your end 😄

To fix the issue run

pip install requests==2.5.3 && pip install docker-compose

[timani]

Thanks @scotty-c, I had the same error and the problem was I had requests 2.2.1 installed.

After specifying requests==2.5.3 it worked for me.

sudo pip install --upgrade docker-compose fixes it
works for me

[lwcolton]

This is still a real problem. By pinning the exact version of requests in setup.py, you prevent anyone from running docker-compose on a system with an upgraded version. For instance, at this time setup.py requires requests < 2.7, when the latest available version is 2.7 So anyone who wants to run the latest version of the requests library on a system with docker-compose... can't. In my testing docker-compose is very much compatible with requests 2.7 So instead of forcing a certain version of that library, it might be nicer to just say "requests >= 2.6.1" or whatever the lowest working version is. Then in the README list the tested version for people who care.

If you're installing using pip, I would highly recommend using a virtualenv, it removes issues like this by isolating the python packages from each other. You can either symlink (or alias) venv/bin/docker-compose or add venv/bin/ to $PATH

[lwcolton]

@dnephin We no longer use virtualenv on our systems because we moved to docker. It seems kind of silly to me to have to activate a virtualenv to run docker-compose commands. Especially since we run them from puppet which complicates using virtualenv.
