Rails rails-stripe-membership -saas安装问题

Question

我对rails非常陌生，我正在尝试克隆一个git并让这个应用程序运行。一切似乎都没问题，但是当我尝试运行rails s时，这就是我得到的错误：

/Users/luizdaluz/.rvm/gems/ruby-1.9.3-p286@rails-stripe-membership-saas/gems/railties-3.2.9/lib/rails/commands.rb:53:in `require': /Users/luizdaluz/rails-stripe-membership-saas/config/application.rb:24: syntax error, unexpected ':', expecting kEND (SyntaxError)
      g.test_framework :rspec, fixture: true
                                       ^
    from /Users/luizdaluz/.rvm/gems/ruby-1.9.3-p286@rails-stripe-membership-saas/gems/railties-3.2.9/lib/rails/commands.rb:53

    from /Users/luizdaluz/.rvm/gems/ruby-1.9.3-p286@rails-stripe-membership-saas/gems/railties-3.2.9/lib/rails/commands.rb:50
    from script/rails:6:in `require'
    from script/rails:6

有人知道如何解决这个问题吗？
