Not compatible with newer Ruby version

unless File.exists?(gitdir)

I think the newer version of Ruby does not support File.exists? any more, instead it use File.exist?
The error I got: "undefined method `exists?' for File:Class (NoMethodError)"

[dep]

Same issue.

undefined method `exists?' for class File (NoMethodError)

    unless File.exists?(gitdir)
               ^^^^^^^^
Did you mean?  exist?
