Your question is unclear. You don't know how to edit a file? Then how are you going to write programs? — Jörg W Mittag, Dec 22 '17 at 16:24

inside your working folder there is file .ruby-version, change the content from 2.3.5 to 2.4.2 and then run steps below, if you working with rbenv

gem install bundler
rbenv rehash
ruby -v 
# make sure it said 2.4.2
bundle install

Just open your Gemfile in a text editor and change the

ruby '2.3.5'

to

ruby '2.4.2'

You need to open your Gemfile and update ruby version ruby '2.4.2' Then you will need to go to terminal and install that version if not already installed. Use rvm use 2.4.3 (if you are using rvm) command to select 2.4.3 version.
