Hello when I install your package and run

iex -S mix

I get the following error message from iex:

** (Mix) Could not start application xmerl: could not find application file: xmerl.app

Am I missing something?
I use elixir 1.2 and OTP 18

hdcos commented

Ok sorry I had to install erlang-xmerl on ubuntu

@hdcos looks like the issue is resolved. Can you close this? :)

kephas commented

How is this closed? I don't see anywhere that the use needs to do anything but mix deps.get. Isn't this a bug?

Hi @kephas,

have you also encountered this problem ? xmerl is part of OTP (as can be seen here: https://erlang.org/doc/applications.html, and here: https://github.com/erlang/otp/tree/master/lib/xmerl). I suggest checking your erlang installation to see if anything is missing

As for @hdcos I had to install erlang-xmerl or I would also get Could not start application xmerl: could not find application file: xmerl.app. I'm using Debian Bullseye/Sid. The fact that xmerl is an OTP application doesn't seem to mean it's always present where Erlang is installed.

Alright, if I understand better your earlier comment, we need to improve the readme and the documentation to ask the user to ensure that his installation of erlang was done including xmerl

kephas commented

Exactly! Sorry if it wasn't clearer before. I hope the PR would do the trick. The needed package is called erlang-xmerl on several systems with apt and yum. I don't know about binary distributions on Windows and MacOS, I've found at least one issue on Github where someone on MacOS was missing xmerl in their setup.

Thanks, I'll keep the issue open for a bit as a reminder for myself to see how I deal with this and the doc for https://hexdocs.pm/
