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
