Can't get youtube_it initialized in my controller

Question

I'm wanting to build an app where I can search for videos on YouTube. It seems the most popular choice is youtube_it gem for doing so.

I added the gem to my Gemfile, and run bundle install. When I do bundle query --local I can see that the gem is preset (version 2.1.4).

So, according to the README it seems to me I should do something like this in my controller(?):

class ConsoleController < ApplicationController  
  .
  .
  .

  def search
    require 'youtube_it'
    client = YouTubeIt::Client.new(:dev_key => "my developer key")
  end
end

But I get "cannot load such file -- youtube_it" error

If I remove the require function, I get "uninitialized constant ConsoleController::YouTubeIt" error.

Does anyone know what I'm doing wrong here?

UPDATE:

/Gemfile.lock

It seems that youtube_it gem is still not installed. Double check that gem 'youtube_it' is included in Gemfile and run bundle update

Alternatively you can also delete Gemfile.lock and then run bundle install
