Question

Can someone tell me why

salvator:edu uko$ ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [x86_64-darwin11.2.0]

and

salvator:edu uko$ rails s
=> Booting WEBrick
=> Rails 3.1.1 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
[2011-11-20 15:26:30] INFO  WEBrick 1.3.1
[2011-11-20 15:26:30] INFO  ruby 1.8.7 (2010-01-10) [universal-darwin11.0]
[2011-11-20 15:26:30] INFO  WEBrick::HTTPServer#start: pid=562 port=3000

ruby versions are different? Can I specify ruby on server start?

UPDATE:

bundle exec rails s works well but what is the correct way to setup ruby/rails and all the stuff, so rails s will work alone as well?

Answer 1

I think you need run rbenv rehash if you are using rbenv.
