Check that you got all the gems needed to trigger the ruby script

gemcheck.sh

#!/bin/bash -e
#
# Wrapper to check all the needed gems are installed

GL=$(gem list)
for gem in $(cat Gemfile | grep -w gem | cut -f2 -d ' '| tr -d "'"); do
    if ! $(echo $GL | grep -wq  $gem); then
        gem install bundler
        bundle install
        break
    fi
done
