Push to heroku rejected during installing Erlang

[vmaark]

Tried several OTP versions but I'm always getting the same error:

I'm new to both heroku and elixir, is there any other information I can provide?

[jesseshieh]

Do you mind pasting the entire git push output? Also, do you have a repo I can use to try and reproduce?

[jesseshieh]

Also have you tried clearing your build cache?

[vmaark]

thank @jesseshieh for the fast reply! I updated the output. I tried heroku repo:purge_cache -a kyria, but did not change the consequent build output.

[vmaark]

Also invited you to the project

[jesseshieh]

Can you also try updating to the latest version of the buildpack? See https://github.com/HashNuke/heroku-buildpack-elixir/blob/master/README.md#use-the-edge-version-of-buildpack

[vmaark]

Thanks @jesseshieh , using the latest source solved the issue!

[jesseshieh]

Awesome!
