looking for docker-compose in the wrong directory

Question

I'm trying to install and use docker-compose. I was using it earlier today and seemed to be throwing errors about my docker-compose file not being the right version, so I tried fixing it by uninstalling it and then reinstalling the latest docker-compose. When I uninstalled it I used pip uninstall. when I reinstalled I used the other way to install docker-compose - using:

sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

So anyway, now when I try and use docker-compose it is throwing this error:

io:~$ docker-compose version
bash: /usr/bin/docker-compose: No such file or directory

See how the paths are different? The new version is installed in:

/usr/local/bin/docker-compose

Where this error says it has been looking in /usr/bin/docker - possibly where the docker-compose that I removed earlier today was installed. Can anybody help me address this problem?

thanks

Answer 1

Check if /usr/local/bin is in your PATH by running:

echo $PATH

If it isn't in the colon separated list of directories, add it to your PATH so bash can find the executable:

export PATH="/usr/local/bin:$PATH"

Answer 2

Check if the installed directory is in the PATH as explained by @Omegamormegil.

After that exit all the terminals and then open the terminal again. Hopefully it should fix the problem.
