The error popsup when i do cities = Cities.cities_in_country('FR')

/cities-0.3.1/lib/cities.rb:30:in has_data?': undefined method exists?' for Dir:Class (NoMethodError)

This is the method involve
def has_data?
data_path && Dir.exists?(data_path)
end

it should be
def has_data?
data_path && Dir.exist?(data_path)
end
