Answer

rbenv needs these at the end of your ~/.bash_profile:

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

Use grep rbenv ~/.bash_profile to see if they're there.

If not, run:

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
exec $SHELL -l

and you should be up and running.

See steps 2 and 3 in the docs for more information.

Additional information on .bashrc, .bash_profile and .profile can be found in:

I'm working with ubuntu 12.04.

This is my ~/.profile file:

# ~/.profile: executed by the command interpreter for login shells.
# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
# exists.
# see /usr/share/doc/bash/examples/startup-files for examples.
# the files are located in the bash-doc package.

# the default umask is set in /etc/profile; for setting the umask
# for ssh logins, install and configure the libpam-umask package.
#umask 022

# if running bash
if [ -n "$BASH_VERSION" ]; then
    # include .bashrc if it exists
    if [ -f "$HOME/.bashrc" ]; then
        . "$HOME/.bashrc"
    fi
fi

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi
export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
eval "$(rbenv init -)"
eval "$(rbenv init -)"

I have installed ruby last version with rbenv and when I try ruby -v I get -bash: ruby: command not found
