Perform a `command -v docker-compose`. See what's really behind that command.

I'd also be interested to know... did you actually type the dash, or
was the command copy/paste. If copy/paste, I've seen unexpected
changes, like substituting an em-dash for a dash. Later, when you
copy/paste the em-dash'd command, things error out.
