Hi ,

Already in your machine 2.3.8 rails version installed,you want to run
2.3.14 rails application.

1.You have to uninstall rails 2.3.8 and install rails 2.3.14 version

gem install rails -v=2.3.14

(Or)

2.Install RVM

RVM: Ruby Version Manager - Installing RVM

Cheers,
Sai

I highly advise using rvm, then you can control the different rails
versions more easily.
