Heroku应用程序无法启动-“需要”:没有要加载的此类文件-SinatratesApp(LoadError)

bamboo-mri-1.9.2 栈。当然,它在Ruby1.9.2上运行良好。但在生产时,在执行时启动时崩溃 config.ru 看起来是这样的:

require 'sinatratestapp'
run Sinatra::Application

我的 .gems 文件:

sinatra --version '>= 1.0'

应用程序本身 sinatratestapp.rb :

require 'rubygems'
require 'sinatra'

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

这就是我在这个项目中所拥有的一切,并尝试在Heroku结果上运行它:

<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.

我试着按照它的指导去做,但作为一个红宝石之角,我的考试没有结果。
