Ruby Forum Ruby on Rails > Trouble with gems on Ubuntu

I'm trying to install rails in my laptop, ubuntu partition, but gems
won't work.  This is what it says:
---
$ sudo gem update --system
/usr/bin/gem:23: uninitialized constant Gem::GemRunner (NameError)
---

Obviously, the error exists here:

---

require 'rubygems'
Gem.manage_gems

required_version = Gem::Version::Requirement.new(">= 1.8.0")
unless  required_version.satisfied_by?(Gem::Version.new(RUBY_VERSION))
  puts "Expected Ruby Version #{required_version}, was
#{RUBY_VERSION}"
  exit(1)
end

# We need to preserve the original ARGV to use for passing gem options
# to source gems.  If there is a -- in the line, strip all options
after
# it...its for the source building process.
args = !ARGV.include?("--") ? ARGV.clone : ARGV[0...ARGV.index("--")]

Gem::GemRunner.new.run(args) #ERROR HERE!!!

What can I do to fix this?

did you use apt-get ?

No.  I used the directions here (note, I used rubygems-1.1.1.tgz
instead):

In usr/bin/gem add

require 'rubygems/gem_runner'

right after the

require 'rubygems'

statement.

Stick with Ubuntu rubygems and spare yourself the headaches. It works
fine even at 0.9.4.
