This worked for me. Gave the same result as you would expect when unziping a ziped folder with subfolders and files.

这对我有用。与子文件夹和文件解压缩ziped文件夹时的结果相同。

Zip::ZipFile.open(file_path) { |zip_file|
     zip_file.each { |f|
     f_path=File.join("destination_path", f.name)
     FileUtils.mkdir_p(File.dirname(f_path))
     zip_file.extract(f, f_path) unless File.exist?(f_path)
   }
  }

Extract Zip archives in Ruby

You need the rubyzip gem for this. Once you've installed it, you can use this method to extract zip files:

你需要rubyzip gem。安装后，可以使用此方法提取zip文件：

require 'zip'

def extract_zip(file, destination)
  FileUtils.mkdir_p(destination)

  Zip::File.open(file) do |zip_file|
    zip_file.each do |f|
      fpath = File.join(destination, f.name)
      zip_file.extract(f, fpath) unless File.exist?(fpath)
    end
  end
end

You use it like this:

你这样使用它：

file_path   = "/path/to/my/file.zip"
destination = "/extract/destination/"

extract_zip(file_path, destination)
