docker-compose gives error "ImportError: No module named ssl_match_hostname" when run as normal user

Question

I've installed docker-compose with 'pip2.7 install docker-compose" but when I try to run it as 'normal' user I get the following error message:

mike@hugin:~/Tobedeleted$ docker-compose  -v
Traceback (most recent call last):

ImportError: No module named ssl_match_hostname

This user is part of the docker group and can run 'docker ps' etc without any issue.

If I try to run 'sudo docker-compose -v' I get the same error.

However, if I run 'sudo su -' first and then issue 'docker-compose -v' I get the expected output.

root@hugin:~# docker-compose -v
docker-compose version 1.11.2, build dfed245

I've tried 'pip uninstall' for various, and all, parts of docker-compose, ssl_match_hostname and then reinstall but nothing seems to resolve it.

I'm now thoroughly stuck - any ideas out there?

Answer 1

you have to reinstall docker-compose using this command:

curl -L https://github.com/docker/compose/releases/download/1.13.0/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose

it worked for me

Answer 2

you should check if docker-compose exist, is installed and running:

$ whereis docker-compose
$ docker-compose --version

check if exist symbolic link pip -> pip2.7 or pip -> pip3.6 by running:

$ sudo pip install docker-compose

Answer 3

This happened to me after updating to Python 3.10. I fixed it by reinstalling docker-compose with:

pip install docker-compose

Note: running yay -S docker-compose on Manjaro didn't work for me.
