Updating Ruby / Rails

August 30, 2009 at 3:45 pm 4 comments

Updating Ruby, Rails and other installed gems is pretty easy.

1 – Run the command “gem outdated”, to see which of your installed gems need updating.

2 – Update the gems itself by running

gem update --system

3 – Then if you want to update all the gems, simply run the command “gem update”. If you’re running the command in Windows, you should probably run “gem update > result.txt”, which will output the results of the command in the text file, so that you can take a look if any error were reported in the process.

4 – Finally, if you made an update of Rails, you will need to manually change the version your project uses by going into config/environment.rb and finding and changing this line:

RAILS_GEM_VERSION = '2.3.3' unless defined? RAILS_GEM_VERSION
