Problems using UUID (universally unique identifier)

Ruby
1

Hi all,

I need to generate uuid numbers. I try to run this:

require_gem ‘uuid’

10.times do
p UUID.new
end

But I’m receiving this:

183260c1-1ad1-012b-bfbf-001c23187f94
uuid.rb:1:Warning: require_gem is obsolete. Use gem instead.
UUID: Initialized UUID generator with sequence number 0xbfbf and MAC
address
00-1C-23-18-7F-94

So I change require_gem with gem. Now I’m receiving this:

uuid.rb:3: uninitialized constant UUID (NameError)

Tool completed with exit code 1

What am I doing wrong?

Just use require:

require ‘uuid’

Or perhaps:

require ‘rubygems’
require ‘uuid’

If you ever needed a specific version of UUID, you could add a gem
statement:

require ‘rubygems’
gem ‘uuid’, '~> 1.0.4"
require ‘uuid’

The example ‘~> 1.0.4’ will be true for all 1.0.x versions where x >=
4, but false for all 1.1 or higher versions (this is the “Pessimistic
Version Constraint” described at
http://docs.rubygems.org/read/chapter/16#page74
if you want more).
