Updating Ruby / Rails
August 30, 2009
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1 – Run the command “gem outdated”, to see which of your installed gems need updating.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

Hi! Is it recommended to run these commands as a super-user (sudo)? I think I did both ways in the past, by mistake.
But everything is working, by the way.

I don’t have that much experience with doing Unix installs, but sudo should work fine
