Mix.Project missing in Elixir/Phoenix prod release

Questions & Help Questions

Am having an issue with Mix.Project being missing in an Elixir/Phoenix prod release - it is needed for a multitenant migration - and is called in Ecto… Any ideas why this would be missing in a release??

What am doing wrong - am using Edeliver/distillery to do the release/deploy

Thanks

Error on the remote_console on the prod instance

Mix is not available in production on purpose. It is a build tool and not meant to give you information during runtime of your project.

If you really have to, you can include :mix in :extra_dependencies, but it will probably not work as you expect when you are in a distillery release, so I think it is best to find another way to implement the feature you need not using or relying on mix.

Thanks the issue was in the apartmentex library and it has been patched… problem solved :slight_smile:
