推荐答案

这对我有用.解压缩包含子文件夹和文件的压缩文件夹时，得到与您预期相同的结果.

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

Zip::Zip.open(file_path) do |zip_file|
  zip_file.each do |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)
  end
end
