Question

My current version of ruby is ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.5.0] but I want to update it to the latest patch level using rvm. How can I

Answer 1

First update RVM:

rvm get stable

Then update your Ruby version:

rvm upgrade 2.0.0

Choose yes for all the questions:

Are you sure you wish to upgrade from ruby-2.0.0-p195 to ruby-2.0.0-p247? (Y/n): Y
Are you sure you wish to MOVE gems from ruby-2.0.0-p195 to ruby-2.0.0-p247?
This will overwrite existing gems in ruby-2.0.0-p247 and remove them from ruby-2.0.0-p195 (Y/n): Y
Do you wish to move over aliases? (Y/n): Y
Do you wish to move over wrappers? (Y/n): Y
Do you also wish to completely remove ruby-2.0.0-p195 (inc. archive)? (Y/n): Y

If you wish to update your gems to the latest versions, you can do:

rvm all do gem update

EDIT: I just did this today for the latest version of ruby 2.0.0 (I updated from ruby-2.0.0-p195 to ruby-2.0.0-p353). After that, I was getting segmentation fault when I tried to update gems. This happens because the gems were installed for ruby-2.0.0-p195 and some of them are incompatible with p353.

Now you can go and try to find the gems that are incompatible, but the easiest solution was to remove all installed gems and install them again. I simply removed gems/ruby-2.0.0-p353 directory that was located in /usr/local/rvm. It could be somewhere else for you.

Then I ran gem install bundler and for each of my rails apps I did bundle install.
