Could not detect rake tasks

heroku

Solution

you can also try enabling user-env-compile

heroku labs:enable user-env-compile

Problem

``` 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! ``` I don't have any rake tasks that I'd like to run automatically. Should I just ignore this warning?
