Money Issues

hi, so I am getting an error thown when I use the Money library that is first introduced in the currency video in ruby development. The first thing that happened was, after I used the command: gem install money, only one gem was installed instead of 3 which is shown in the video.

Later, when I started using the library, I saw when I typed the following command: 

money = Money.new(1000)

this message was printed:

#<Money fractional:1000 currency:USD>

this is different from the one received in the video, since it is:

#<Money cents:1000 currency:USD>

when I tried to print out the variable that the money library was being used for, I ran into this error:

puts money
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

I would just like to know if anyone knows if this is a bad thing, if I have to install the missing gems, or what is going on in general. I am on a mac osx 10.8.5 and I have 1.9.3-p484 installed for ruby.

EDIT

ok, so the last error has gone away, but I guess I would like to know why there was only 1 gem installed and why mine says fractional.

It may say that only one gem was installed because the other ones may have already been installed. I can't help much because I don't seem to know which video you're referring to?

require 'money'
m = Money.new(1000)
 # => #<Money fractional:1000 currency:USD>

The fact that it only shows the two instance variables, which you can check for like...

m.instance_variables
 # => [:@fractional, :@currency, :@bank]

...doesn't matter because cents is a method (as m.methods.include? :cents is true). And when you do this...

m.cents
 # => 1000

...you get the value you saw. This may be because we are using a newer version of the money gem and the functionality may have changed.
