WEBrick rails server is not working

Today i have installed Ruby (ruby 2.2.3p173 (2015-08-18 revision 51636) [x64-mingw32]) and rails gem (rails 4.2.4)

I am following a proceedure set out in a series of tutorial videos about rails. I have the following version of myqsl 2 installed (and reinstalled in case it was a dirty install) mysql2-0.4.1-x64-mingw32

This question pertains to a application called simple_cms created in the following fashion as per instructions on the tutorials

rails new simple_cms -d mysql

I have:

• run bundle install a few times
• used gem cleanup
• run bundle exec rails server
• tried to rake db:create and bundle exec rake:db create each method as suggestedhere
• reinstalled mysql2 a few times

However upon input of

rails server

in the root of my project simple_cms. WEBrick fails to even kick off

By way of example in other similar questions here and here, both of the inquirers receive the following

=> Booting WEBrick
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

etc ..etc....before the failure of WEBrick. However I do not eve get this far as there is no mention of anything to do with WEBrick. Below is the error message I receive after typing the rails server command:

What can be done to rectify this situation as i am now going round in circle trying the same thing over and over again , and as Einstein rightly stated the definition of insanity is doing the same thing over and over again and expecting different results.

Many thanks in advance
