Question

I have a problem others had before but I can’t get anywhere with the answers I found online. When I do:

require "juggernaut" 

in IRB or when I execute a Ruby file with

ruby test.rb

I get

no such file to load -- juggernaut

The solution is to add juggernaut to my Gemfile, right?

But where in Redmont is this magical Gemfile? It’s not where the Rakefile is. Maybe I have to create a brand new Gemfile from scratch? How would that look like?

And how is “bundler” involved in all this?

Thanks guys!

Answer 1

Yes, you’ll need to create Gemfile. Bundler will cheerfully do this for you:

$ bundle init
Writing new Gemfile to /foo/bar/Gemfile

$ cat Gemfile
# A sample Gemfile
source "http://rubygems.org"

# gem "rails"
