I came across this middleman package
GitHub - thenickcox/Middleman-Skeleton: A port of the Skeleton Responsive framework for use with Middleman, HAML, and Sass 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
Any help would be helpful!
