The first step is to install some dependencies for Ruby. 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 sudo apt-get install libmysqlclient-dev sudo apt-get install libpq-dev sudo apt-get install imagemagick sudo apt-get install libmagickwand-dev The installation for rvm is pretty simple: sudo apt-get install libgdbm-dev libncurses5-dev automake libtool bison libffi-dev curl -L https://get.rvm.io | bash -s stable source ~/.rvm/scripts/rvm echo "source ~/.rvm/scripts/rvm" >> ~/.bashrc rvm install 2.1.2 rvm use 2.1.2 --default ruby -v The last step is to tell Rubygems not to install the documentation for each package locally echo "gem: --no-ri --no-rdoc" > ~/.gemrc Installing Rails sudo add-apt-repository ppa:chri...
