Error : Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0

Error :

ganesh$ rails s
Your Ruby version is 1.9.3, but your Gemfile specified 2.0.0

Solution :

If you type rvm list and it shows a 2.0 version of ruby as your current version and you are still getting this error,typing rvm use (ruby version) fixed this issue

1. ganesh$ rvm list
rvm rubies
=* ruby-1.9.3-p429 [ x86_64 ]
ruby-2.0.0-p247 [ x86_64 ]
ruby-2.1.0 [ x86_64 ]
# => – current
# =* – current && default
# * – default

2. ganesh$ rvm use ruby-2.0.0-p247
Using /Users/ganesh/.rvm/gems/ruby-2.0.0-p247

3. ganesh$ rails s
