ruby - 如何在输出中换行

Question

如何使 \n 在我的输出中实际工作？目前它只是把它全部写在 1 个长 block 中。感谢您的帮助

Dir.chdir 'C:/Users/name/Music'
music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
puts 'what would you like to call the playlist?'
@new = ''
playlist_name = gets.chomp + '.m3u'

music.each do |z|
  @new += z + '\n'
end

File.open playlist_name, 'w' do |f|
  f.write @new
end

Answer 1

使用"\n"代替'\n'
