Why is Heroku push failing from Cloud9?

Question

I signed in to Heroku through my Rails app but when I go to push, I get this error:

    -----> Ruby app detected
    -----> Compiling Ruby/Rails
   sh: 1: Gemfile: not found
   !
   !     There was an error parsing your Gemfile, we cannot continue
   !     
   !     [!] There was an error parsing `Gemfile`: syntax error, unexpected
          keyword_end, expecting end-of-input. Bundler cannot continue.
   !     
   !     #  from /tmp/build_68de181abe890ef0e6c625b9af15fb4a/Gemfile:63
   !     #  -------------------------------------------
   !     #    end
   !     >  end
   !     #
   !     #  -------------------------------------------
   !
   !     Push rejected, failed to compile Ruby app.
   !     Push failed

I can't find this error in my gemfile:

  source 'https://rubygems.org'

 end

 group :production do

错误消息指出，在第63行有一个额外的end 。如果您已将其从Gemfile中删除，请确保提交更改，然后尝试再次推送。
