Elixir phoenix web application broke after pushing to heroku

While trying to push my elixir phoenix web application to heroku I had quite a few issues which took pretty long to solve, but after I finally did... my application won't start anymore!

I'm still really new to elixir and phoenix and even heroku, so this is really a mystery for me.

When running mix phoenix.server this is my output:

** (UndefinedFunctionError) function Phoenix.Template.hash/2 is undefined or private. Did you mean one of:

  * hash/1

(phoenix) Phoenix.Template.hash("web/templates/error", "*")
web/views/error_view.ex:1: Dashboard.ErrorView.__phoenix_recompile__?/0
(elixir) lib/stream.ex:429: anonymous fn/4 in Stream.filter/2

(mix) lib/mix/tasks/run.ex:86: Mix.Tasks.Run.run/5
(mix) lib/mix/tasks/run.ex:54: Mix.Tasks.Run.run/1

Now, I don't really understand where this problem has come from and it seems very confusing to me and I would love some help.

I don't even know which files to share so you can maybe get some more information, but I'm willing to post any code in my project.

I had the same issue locally, and if you're working on multiple branches (which have multiple phoenix releases) ensure to rebuild dependencies, that might just be the issue.

I had exactly the same problem. In my case it was due to bad elixir and erlang version. I solved it by installing erlang 18.2 and elixir 1.2.3

I suggest using version managers for erlang and elixir (I used kerl and envex)
