Error while installing rb-appscript gem

Question

I want to create a rails app using Test-Driven Development (TDD), so i wrote

rails new myproject -T

then I added these lines of code in the gemfile

group :test, :development do
    gem 'turn'
    gem 'rspec-rails'
    gem 'capybara'
    gem 'guard-rspec'
    gem 'growl_notify'
end 

so i tried to install the bundle but i got this error while bundling

An error occured while installing rb-appscript (0.6.1), and Bundler cannot continue.
Make sure that `gem install rb-appscript -v '0.6.1'` succeeds before bundling.

so i tried to install the gem manually

gem install rb-appscript -v '0.6.1'

i got this similar error too

Answer 1

Growl is for Mac OS X only, instead of growl_notify you probably want:

gem 'libnotify'
