Im trying to deploy my app but get this error:

 !     Push rejected, failed to compile Elixir app.
 !     Push failed

   * Erlang 23.3.2
   * Elixir v1.12.2

What am I doing wrong?

I don’t know about the specifics of deploying to Heroku, but in general this means you’re missing a library.

A similar example of this errror happens if you compile on one OS but your target OS is different e.g., you compile on ubuntu but deploy using alpine.

Here’s a good resource that explains it far better than I ever could: Cross-compiling Elixir releases with ASDF and Docker

Edit: this could also be very useful: GitHub - bitwalker/distillery: Simplify deployments in Elixir with OTP releases!

For libtinfo.so.5 it’s more specifically ncurses.
