Installing Ruby via rbenv fails

Problem: I installed ruby, but it is not recognized correctly. I'm following the deploying to VPS: https://github.com/railscasts/335-deploying-to-a-vps

I am setting my server on ubuntu 12.04 LTS to deploy my rails app. I'm following the railscast on deploying to a VPS, and trying to install ruby through rbenv. It seemed everything was installed correctly, but when I tried to check the ruby version, it gave me errors. The following are the commands that I ran.

deployer@max:~$ rbenv install 1.9.3-p125

deployer@max:~$ rbenv global 1.9.3-p125
deployer@max:~$ ruby -v
'ruby' program can be found in the following packages:
 * ruby1.8
 * ruby1.9.1

How do I solve this?

You should restart the shell to allow rbenv to find the new Ruby

$ exec $SHELL
$ ruby -v

ruby 1.9.3p194 (2012-04-20 revision 35410) [i686-linux]

You don't need to use rbenv to install a specific version of Ruby. Instead use ruby-build to install 1.9.3-p125 into /usr/local:

ruby-build 1.9.3-p125 /usr/local/

Or, install Ruby manually:

# Compile Ruby (instead of rbenv)
sudo apt-get -y install build-essential zlib1g-dev libssl-dev libreadline5-dev libyaml-dev
wget ftp://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p125.tar.gz
tar -xvzf ruby-1.9.3-p125.tar.gz
cd ruby-1.9.3-p125/
./configure --prefix=/usr/local
make
sudo make install
sudo gem install bundler --no-ri --no-rdoc

Maybe you are missing

eval "$(rbenv init -)";

in your shell config
