Anyone understand why I might be getting this error…

$ middleman init testsite --template=html5
create testsite/Gemfile
run bundle install from “.”

Depending on your setup, here are some things you can try (start at the top of the list and work your way down till you (hopefully) find something that works

bundle update

bundle install

gem update tzinfo tzinfo-data
bundle update

gem uninstall tzinfo tzinfo-data
gem install tzinfo tzinfo-data
bundle install
