How to install Ruby 2.1.4 on Ubuntu 14.04

First of all, install the prerequisite libraries:

sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential
libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3
libxml2-dev libxslt1-dev libcurl4-openssl-dev
python-software-properties libffi-dev

Then install rbenv, which is used to install Ruby:

cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo ‘export PATH=”$HOME/.rbenv/bin:$PATH”‘ >> ~/.bashrc
echo ‘eval “$(rbenv init -)”‘ >> ~/.bashrc
exec $SHELL

git clone git://github.com/sstephenson/ruby-build.git
~/.rbenv/plugins/ruby-build
echo ‘export PATH=”$HOME/.rbenv/plugins/ruby-build/bin:$PATH”‘ >> ~/.bashrc
exec $SHELL

rbenv install 2.2.0
rbenv global 2.2.0
ruby -v

Then (optional) tell Rubygems to not install local documentation:

echo “gem: –no-ri –no-rdoc” > ~/.gemrc
