RubyGems 1.5.0 and 1.5.1 shipped with a broken gem update --system. You will need to use the Manual Upgrade Recipe below.
Use the Normal Upgrade Method below. (finally!)
Use the Normal Upgrade Recipe below.
RubyGems 1.1 and 1.2 have problems upgrading when there is no rubygems-update installed. You will need to use the following instructions if you see “Nothing to update”.
Use the Manual Upgrade Recipe below.
Use the Normal Upgrade Recipe below.
$ gem update --system 1.3.7
Use sudo/su as appropriate:
$ gem install rubygems-update -v 1.3.7 $ update_rubygems _1.3.7_
Replace 1.3.7 with whatever version you want to downgrade to. This recipe can also be used to upgrade to a specific version instead of the latest.
Do make sure that you don’t have any other versions of rubygems-update installed when you run the second command.
Use sudo/su as appropriate:
$ ruby --disable-gems -S gem which rubygems ~/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/rubygems.rb $ rm ~/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/rubygems.rb $ rm -rf ~/.rvm/rubies/ruby-1.9.2-p136/lib/ruby/site_ruby/1.9.1/rubygems $ gem -v 1.3.7
Use sudo/su as appropriate:
$ gem update --system
If you have an older version of RubyGems installed, then you can still do it in two steps:
Use sudo/su as appropriate:
$ gem install rubygems-update $ update_rubygems
If you don’t have any RubyGems install, there is still the pre-gem approach to getting software, doing it manually:
Use sudo/su as appropriate:
-
Download from: rubygems.org/pages/download
-
Unpack into a directory and cd there
-
Install with: ruby setup.rb
