require 'sinatratestapp'
run Sinatra::Application

我的.gems文件：

sinatra --version '>= 1.0'

而应用本身就是sinatratestapp.rb：

require 'rubygems'
require 'sinatra'

get '/' do
  "Hello from Sinatra on Heroku!"
end

这就是我在项目中所做的一切,并试图运行Heroku的结果：

<internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- sinatratestapp (LoadError)
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from config.ru:1:in `block (3 levels) in <main>'
        ...
-----> Your application is requiring a file that it can't find.

       Most often this is due to missing gems,or it could be that you Failed
       to commit the file to your repo.  See http://docs.heroku.com/gems for
       more information on managing gems.

       Examine the backtrace above this message to debug.

我试图做,因为它指导,但作为一个Ruby noob我的考试没有产生任何结果.
