rails command working . rails -v shows 4.0.0 . gem list rails shows 3.2.13 . want work on rails 3.2.13 , when tried uninstall rails 4.0.0 says gem "rails" not installed .what should rails -v shows 3.2.13 , rails 4 uninstalled ?

it's because rails binary loads via railties gem. last 2 lines of /usr/local/bin/rails looks like:

gem 'railties', version load gem.bin_path('railties', 'rails', version) 

you need run:

gem uninstall railties -v 4.0.0 

assuming have rails & railties 3.2.13 installed, rails -v should return rails 3.2.13.
