Rails NoMethodError（Hyperclient:Module 的未定义方法“新”）

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 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.
