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 

   https://rvm.io/rvm/install/ 

Cheers,

Sai

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

But my other apps are running
this is the only line i have in my config/environment.rb file
RAILS_GEM_VERSION = '2.3.8' unless defined? RAILS_GEM_VERSION

[sameena Khan]

my other apps are on 2.3.8 only those are going fine with the same gems
