Vagrant up not working

[temitopeog]

Changed to path quickstart/rancher/vagrant and ran vagrant up

Got the following err:

Vagrant failed to initialize at a very early stage:

There was an error loading a Vagrantfile. The file being loaded
and the error message are shown below. This is usually caused by
a syntax error.

Path: /quickstart/rancher/vagrant/Vagrantfile
Line number: 7

Message: NoMethodError: undefined method `exists?' for class File

Line 7 of Vagrantfile is:

if File.exists?(File.join(File.dirname(FILE), "local_config.yaml")) then
puts "Using local configuration file"
x = YAML.load_file(File.join(File.dirname(FILE), "local_config.yaml"))
else

any help, please?

Thanks

Inside of Vagrantfile, and change File.exists into File.exist
