For Ruby applications, managing dependencies manually can be difficult. Luckily RVM is there to make everything easier on us. RVM manages different Ruby versions, dependencies, and gem versions. It is hugely helpful in getting Ruby and Rails installed quickly and easily.
Log into the root account, then install the dependencies:
-y install build-essential openssl libreadline6 libreadline6-dev curl
git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3
libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool
bison subversion python. After you install that, we need to download RVM
and install RVM and Rails 1.9.3:
curl -L https://get.rvm.io | bash -s
stable --rails --autolibs=enabled --ruby=1.9.3.
Now you have Ruby and Rails ready to do your bidding.
