On Riding the Latest Rails
December 29, 2011 § Leave a Comment
Note: I wrote this up a few weeks a go, but didn’t publish it for some reason. It is a touch out of date since Rails 3.2 RC1 was recently released, but should be close enough to give you a good idea on how to get up and running on Rails master.
I wanted to play with the latest and greatest for Rails, which at the time of writing is 3.2.0.beta (RC 1 is now out). This means building and installing the rails gem locally. It took me a good while to figure out how to get everything working, so I figured I’d throw it down here for future reference… and for anyone else running into the same problems I did.
I am using rvm to isolate my different gem set ups, so as not to get random version conflicts. These are the lists of commands with notes I ran to get everything up and running:
# create a new gemset to use with rails master rvm gemset create rails-master rvm gemset use rails-master # this is where I am going to put all of the git repos cd ~/src # Rails 3.2.0.beta requires the most recent (as in master) # versions of arel and journey git clone git://github.com/rails/arel.git cd arel gem build arel.gemspec gem install arel-*.gem cd .. git clone git://github.com/rails/journey.git cd journey gem build journey.gemspec gem install journey-*.gem # now get Rails cd .. git clone git://github.com/rails/rails.git cd rails # install all of the Rails pieces, # i.e., ActiveRecord, ActiveSupport, etc... cat RAILS_VERSION | xargs ruby install.rb # check to make sure you are riding the correct rails ruby -r 'rails' -e 'puts Rails::VERSION::STRING'
You can get just the commands in a gist too.
