Installing Gems?

The last few videos we've been using IRB to run Ruby code. Now in this video we're supposed to "gem install money". Jason doesn't say we've changed what we're typing into, but I instantly get a "NameError" when trying to type this in IRB.

I've googled it but can't find a useful solution. Can someone help? Thanks!

Okay, I found that it installs in the command line. In Windows, this looks different than what Jason uses, which I expect is a Mac, which I am still unfamiliar with. With Ruby 1.9 versions, I think that RubyGems is installed automatically. At the command line, you can type "gem -v" to see which version you are running and that it is successfully installed.

And I am answering myself so others won't have to! :)
