What does this error while running 'middleman' mean?

#1

I came across this middleman package and tried to run it with bundle exec middleman server but get this back in the terminal…

The source :rubygems is deprecated because HTTP requests are insecure. Please change your source to 'https://rubygems.org' if possible, or 'http://rubygems.org' if not.
== The Middleman is loading
== Port 4567 is unavailable. Either close the instance of Middleman already running on 4567 or start this Middleman on a new port with: --port=4568

I don’t have any other servers running, so not sure what the problem is, any help would be fantastic…

#2

Perhaps one instance of Middleman didn’t quit cleanly? This has happened to me before.

Try

lsof -i:4567

And see if there are any processes running. If so, you’ll be provided the process id and you can do:

kill -9 <PID here>

Hope this helps.

Hey thanks Todd! I’ll have to try that!
