Rails NoMethodError (undefined method `new' for Hyperclient:Module) - ruby-on-rails

Question

This is quite a 'newbie' question but I've been searching and can't seem to find anything to solve an error with using hyperclient in a rails app, in one of my Model's methods.
Whenever I run rails c I get the error
NoMethodError (undefined method `new' for Hyperclient:Module)
In my gemfile
gem "hyperclient"
-- ran bundle install
in model app/models/artwork.rb
class Artwork < ApplicationRecord
require "hyperclient"
def self.test_artsy
api = Hyperclient.new('https://api.artsy.net/api') do |api|
puts api
end
end
end
I've looked at the docs on hyperclient and have seen that they do have a method for .new (also on their examples) so I know it's something I've done incorrectly but I'm not sure what else to try?
The code did work when opening irb in the terminal.

Answer 1

You haven't specified any version in your Gemfile so it might happen that Bundler will not install the latest version and that's what I am guessing might happened here.
You can check which version is installed by doing:
cat Gemfile.lock | grep hyperclient
You have at least two options here:
1)
bundle update hyperclient - this should update your Gemfile.lock to the latest version
2)
bundle remove hyperclient
bundle add hyperclient --version "0.9" - this will update your Gemfile and then run bundle install that will regenerate your Gemfile.lock
The second option is recommended since it is a good practice to always specify version for the gems you are using.
