rubyzip - cannot load such file -- zip

I am attempting to use rubyzip to create zip archives on the fly in my app. I'm using their readme as a starting point. I added the gem to my Gemfile:

gem 'rubyzip'

Then ran bundle install and restarted the rails server.

My controller code is:

require 'rubygems'
require 'zip'

filename = "#{Time.now.strftime('%y%m%d%H%M%S')}"
input_filenames = ["#{filename}.txt"]
zip_filename = "#{filename}.zip"

Zip::File.open(zip_filename, Zip::File::CREATE) do |zipfile|
  input_filenames.each do |f|
    zipfile.add(f, directory + '/' + f)
  end
end

The error I'm getting is: cannot load such file -- zip

I've tried require 'zip/zip' but it produces the same error.

Thanks in advance!

I suggest you to use:

gem 'rubyzip',  "~> 1.1", require: 'zip'

and then require 'zip' in your controller should work fine.

Interface of rubyzip was changed. You using old version. Docs on rubydoc.info from master branch.

You might be looking at an example that's too new.

If you are using Rubyzip 0.9.x, then you need to follow this example:

(require "zip/zip", then use Zip::ZipFile instead of Zip::File)

require 'zip/zip'

folder = "Users/me/Desktop/stuff_to_zip"
input_filenames = ['image.jpg', 'description.txt', 'stats.csv']

zipfile_name = "/Users/me/Desktop/archive.zip"

Zip::ZipFile.open(zipfile_name, Zip::ZipFile::CREATE) do |zipfile|
  input_filenames.each do |filename|
    # Two arguments:
    # - The name of the file as it will appear in the archive
    # - The original file, including the path to find it
    zipfile.add(filename, folder + '/' + filename)
  end
end
