How do I set up Ruby on Rails?

Question

I am interested in setting up a Ruby on Rails environment on my 10.10 laptop.

Is there anything special I need to keep in mind for installation (i.e. that could be new or unique to 10.10)?

Are there any suggested walkthroughs that I could follow along with?

Thanks in advance.

Answer 1

There are many ways of install ruby.

1. RVM. This is the 'traditional' way that is used by many rubyists.

2. rbenv (answer coming)

3. From packages.

4. From source (answer coming).

Answer 2

This question has an answer which leads to a much more interesting "how-to" article "Ubuntu, Ruby, RVM, Rails, and You" guiding us through a fresh install of Ruby (and related things), starting from rvm. It adds insights and provides a lot of remarks for beginners -- because Ruby is truly something awful to get setup when one is without all that background knowledge and support.

The article was last updated on October 11th, 2012 and should install Ruby 1.9.3, RVM and Rails 3.2.8.

I'm posting this answer for the sake of linking the related questions.

Answer 3

From packages.

Install the following packages.

ruby1.9.1-full , ruby1.9.1-dev , libpq-dev (only libpq-dev if you're doing ruby on rails development as well.)

I've been using this fantasic one-liner for rails 3.2 w/ruby 1.9.3, RVM, etc,

wget --no-check-certificate https://raw.github.com/joshfng/railsready/master/railsready.sh && bash railsready.sh

Answer 5

rvm.

rvm has a really nice installer.

First, install curl .

Then you need to install the dependencies:

sudo apt-get 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 libpq-dev

Now, you can use the automated installer:

curl -L https://get.rvm.io | bash -s stable --ruby

After that, log out and then log back in, and you're all set!

ruby -v should return something like:

ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-linux]

If it doesn't, then you should look at the troubleshooting page for RVM.
