   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!

我没有任何我想自动运行的rake任务.我应该忽略这个警告吗？
