Sam Ruby: RubyGems 1.3.1 on Ubuntu 8.10

What happens when Ubuntu wants to update rubygems?

Posted by Joe at 19:56

That’s a better error message than I get on Hardy.

$ sudo gem update --system

Updating RubyGems

Nothing to update

$ sudo gem update --debug --system

Exception `NameError' at /usr/local/lib/site_ruby/1.8/rubygems/command_manager.rb:134 - uninitialized constant Gem::Commands::UpdateCommand

Updating RubyGems

Nothing to update

Upgrading using

apt-get install rubygems

on 8.10 only brings you up to 1.2.0.

Using update_rubygems directly on a virgin 8.10 system doesn’t work for me, but does provide an alternate means to get access to a


that does do the trick.

$ sudo gem install update_rubygems $ sudo update_rubygems sudo: update_rubygems: command not found $ sudo /var/lib/gems/1.8/gems/rubygems-update-1.3.1/bin/update_rubygems Error: Cannot find RubyGems Update Path! RubyGems has already been updated. The rubygems-update gem may now be uninstalled. E.g. gem uninstall rubygems-update $ cd /var/lib/gems/1.8/gems/rubygems-update-* $ sudo ruby setup.rb $ gem -v 1.3.1

$ sudo gem install update_rubygems $ cd /var/lib/gems/1.8/bin $ sudo ./update_rubygems $ gem -v 1.3.1 $ sudo gem install rails

I also seem to need


installed in order to run

In order to avoid conflicts with system updates wouldn’t it make more sense to change GEM_HOME to allow non-super install? I would post a link with more info but I am on my phone.

What version of Ruby are people using on Ubuntu 8.10 for Rails development? Are people using the supplied 1.8.7?

update rubygems

sudo gem install rubygems-update
sudo update_rubygems

should help with automating rubygem 1.3.1 installation...which is always a pain

ruby setup.rb

rails 2.2 installation in Intrepid Ibex 8.10.

gem update --system is disabled on Debian. gem competes with apt-get

cd /var/lib/gems/1.8/bin

actualizar ruby gems en ubuntu o debian

$ sudo ruby setup.rb $ gem -v

$ gem -v 1.3.1 $ sudo gem install rails Successfully installed rake-0.8.3 Successfully installed activesupport-2.2.2
