Create Directory if it doesn t exist with Ruby

Question

I am trying to create a directory with the following code:

Dir.mkdir("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test")
    unless File.exists?("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test")

However, I'm receiving this error:

No such file or directory - /Users/Luigi/Desktop/Survey_Final/Archived/Survey/test (Errno::ENOENT)

Why is this directory not being created by the Dir.mkdir statement above?

You are probably trying to create nested directories  Assuming foo does not exist  you will receive no such file or directory error for   Dir mkdir  foo bar      gt  Errno  ENOENT  No such file or directory -  foo bar    To create nested directories at once  FileUtils is needed   require  fileutils  FileUtils mkdir p  foo bar      gt    foo bar     Edit2  you do not have to use FileUtils  you may do system call  update from  mu is too short comment     gt  system  mkdir    -p    foo bar    worse version  system  mkdir -p  foo bar     gt  true   But that seems  at least to me  as worse approach as you are using external  tool  which may be unavailable on some systems  although I can hardly imagine system without mkdir  but who knows
