In Ruby, how could I do:

mkdir -p cool/beans

1. Here's what I came up with:

   Dir.mkdir('cool') unless File.directory?('cool')
   cool_beans_path = File.join('cool', 'beans')
   Dir.mkdir(cool_beans_path) unless File.directory?(cool_beans_path)
   

   But, isn't there a better way?

2. I know I could do:

   system('mkdir', '-p', File.join('cool', 'beans'))
   

   But, that's not platform independent, is it? Like, it works on Mac but not on Windows, right?

回答1:

require 'fileutils'
FileUtils.mkdir_p 'cool/beans'
