Unable to make :password work ('no implicit conversion of Hash into String')

[DannyBen]

I must be missing something obvious, but I am unable to make rye connect to my local vagrant box that is password protected (not SSH key).

This is what I tried:

puts "Works, but prompts for pass"
rbox = Rye::Box.new
p rbox.pwd.to_s

puts "Fails"
rbox = Rye::Box.new user:user, password:password
p rbox.pwd.to_s

puts "Fails"
rbox = Rye::Box.new user:user, password:password, password_prompt:false
p rbox.pwd.to_s

This is the output trace I get
