can't convert Fixnum into String

[zeroasterisk]

I've stripped out most of my config, down to just the basics and I'm still getting this error... I don't see anywhere in here where the "string" is a "fixnum"

$ mina deploy_prod --trace

** Invoke deploy_prod (first_time)
** Execute deploy_prod
** Invoke deploy (first_time)
** Execute deploy
** Invoke git:clone (first_time)
** Execute git:clone
mina aborted!

Tasks: TOP => deploy_prod

Here's my deploy_prod task and the deploy task, totally stripped down...

desc "Deploy to Production Servers"
task :deploy_prod do
  set :env, 'prod'
  isolate do
    domains_prod.each do |domain|
      set :domain, domain
      invoke :deploy
      run!
    end
  end
end

desc "Deploy (Single Deploy Command)"
task :deploy do
  deploy do
    invoke :'git:clone'
  end
end

And here's the basis for this approach:

I think this is caused because of Ruby 1.8. Try running it with 1.9+.

[prohfesor]

confirming works on 1.9 and reproducible on 1.8, ubuntu 12.04

Im having the same issue: (while calling mina deploy --trace in jenkins task)

mina aborted!

[jerefrer]

What if I want to use mina with an app running on 1.8.7 ?
Wouldn't there be a quick workaround for this ?

[gabskoro]

Fixed, please update the gem to version 0.3.1 :)
