Update Ruby to Install Rails on macOS 5.3 Server

I thought there might be an easier way to do this. So there’s this binary called serverrails that I assumed would install rails – no wait, actually it’s a ruby script that tells me to ‘gem install rails’ – which fails:

cat `which serverrails`
#!/usr/bin/ruby
# Stub rails command to load rails from Gems or print an error if not installed.
require 'rubygems'

version = ">= 0"
if ARGV.first =~ /^_(.*)_$/ and Gem::Version.correct? $1 then
version = $1
ARGV.shift
end

begin
gem 'railties', version or raise
rescue Exception
puts 'Rails is not currently installed on this system. To get the latest version, simply type:'
puts
puts ' $ sudo gem install rails'
puts
puts 'You can then rerun your "rails" command.'
exit 0
end

load Gem.bin_path('railties', 'rails', version)

Given that doesn’t work, we can just do this the old fashioned way… First let’s update rails to 2.2 or 2.2.4 using rvm, so grab the latest rvm and install it into /usr/local/rvm:

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

Then fire it up:

sudo source /etc/profile.d/rvm.sh

Then install the latest ruby:

sudo rvm install 2.2

Set it as default:

sudo rvm use 2.2 –default

Then run your gem install:

gem install rails
