rubygems – 安装rb-appscript gem时出错

rails new myproject -T

然后我在gemfile中添加了这些代码行

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

所以我试图安装捆绑,但我在捆绑时遇到此错误

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.

所以我试图手动安装宝石

gem install rb-appscript -v '0.6.1'

我也得到了类似的错误

所以任何建议我现在能做什么？
