Could not detect rake tasks
ensure you can run `$ bundle exec rake -P` against your app with no environment variables present
and using the production group of your Gemfile.
This may be intentional, if you expected rake tasks to be run
cancel the build (CTRL+C) and fix the error then commit the fix:
rake aborted!

我能够在几个小时前用我的最后一次提交进行分段。这个新提交只有一些css和jquery更改，现在它已经坏了。 我能够创建一个新的应用程序（staging2）并部署代码。然后我尝试部署到生产（危险，我知道），这一切都很好。那么我的登台应用程序发生了什么？
更新：添加我的application.rb文件。
