I downloaded and installed ruby 2.1.0.

Here's the output of ruby -v:

ruby 2.1.0p0 (2013-12-25 revision 44422) [i686-linux]

So I specified the same version in my Gemfile. But when I run bundle, I get:

Your Ruby version is 1.9.3, but your Gemfile specified 2.1.0p0

And to add on, rvm list does not give me the list of rubies:

rvm rubies


$>

I'm new to Ruby and all I want to do is use the new Ruby version. Any idea what could be wrong?

    You should use rvm to install ruby `rvm install 2.1.0` – Bart Jan 01 '14 at 18:34

    at first type `rvm reset`, then `rvm list`, say if will not help – Малъ Скрылевъ Jan 01 '14 at 18:50

    @Jani: Why should we do that? – AGS Jan 01 '14 at 19:30

    `rvm use system` would use system ruby (the one you installed manually) and not one installed via rvm, however preferably install it via rvm (`rvm install 2.1.0`) – bjhaid Jan 01 '14 at 19:56
  • Here's the output of **rvm install 2.1.0**: `ERROR: Unknown ruby interpreter version: '2.1.0' ERROR: Either the ruby interpreter is unknown or there was an error!.` – splatoverflow Jan 02 '14 at 02:29
  • @AGS rbenv manages the different rubys in far more simpler ways. – Jahan Zinedine Jan 02 '14 at 09:33
  • @Jani, but rbenv itself does not install rubies, which gets a lot more confusing for beginning users, and if you are in a search for simplicity you should checkout chruby => https://github.com/postmodern/chruby and ruby-install => https://github.com/postmodern/ruby-install – mpapis Jan 02 '14 at 15:12
  • Found the [solution](http://stackoverflow.com/questions/9056008/installed-ruby-1-9-3-with-rvm-but-command-line-doesnt-show-ruby-v/9056395#9056395). It seems Ubuntu does something to RVM that causes it to break. Reinstalled using the instructions from the answer given to that question and things started working out from there. Thanks for your help guys! – splatoverflow Jan 02 '14 at 17:56

starting with http://rvm.io/help you can find http://cheat.errtheblog.com/s/rvm and http://screencasts.org/episodes/how-to-use-rvm - make sure to read / watch both - in few minutes they should make it all clear.
